Quite possible, for sure. The US Patent and Trademark Office has an extensive patent research engine on its website, although I've never figured out exactly how to use it efficiently. I ran a general search for the number and got nothing. That doesn't mean it isn't there. There were many, many maritime patents, and lots and lots of "also rans" that never came to anything. Some are quite entertaining, If you take the time to wade through all the hits for "lifeboat," etc., you may be able to find the patent application that matches this model. Good luck!

Yes, "patent models" were once required to be submitted with every patent application. The US Patent and Trademark Office had warehouses full of them going back to the beginning of the government. They eventually dropped the physical model requirement and back in the 1970's or so, as I recall, they cleaned house, retaining some of the historically remarkable ones, which went to the Smithsonian, which once exhibited Abraham Lincoln's patent model for his "Improved Method of Bouying Vessels Over Shoals." https://en.wikipedia.org/wiki/Abraham_Lincoln's_patent
 

 
The rest of the old Patent Office models were sold off to the public and snatched up by antique dealers, finding their way via the retail market to bookshelves and mantles as decorator pieces. I once had a patent attorney colleague who decorated his large patent law firm's offices with them. This could very well be an old Patent Office Model. The models had to depict the invention that was sought to be patented, so they were often partial models with the focus on the patentable aspect of the thing. In this instance, there may have been something inside the model hull that was the focus of the invention and somebody who wanted the hull pulled that out with the intention of building something else inside the hull, but never got around to it.

I don’t believe that this model was ever completed or perhaps ever intended to be completed.  Assuming that this is a model of a lifeboat,  there would be a “rising strake” running around the inside of the frames on each side to support the thwarts, the seats that people sat on.  There is no evidence that one was ever attached.
 
Lifeboats were framed with closely spaced steam bent frames of small cross sectional dimensions; to minimize weight.  This model is framed with fewer widely spaced frames sawn to shape.  It is possible that whoever built the model was trying to demonstrate a construction technique in hopes of securing a patent.
 
If you can figure out its provenance it might have some real value.

It apperas to be a boat design that was submitted to the U.S. Patent office for approval. It would be nice if it were possible to have a clear picture of the rest of the inscription on the stem post by the F19083. Models of invention, devices or their improvement were often submitted when a drawing or the actual object was not possible. The boat is a keeper' Hope this shed some light on what you have. By the way what was your grandfather's profession?

For much the same reason as any other work of art. If an amateur grandparent painted a picture of a subject that had been painted many, many times before (particularly a "paint-by-numbers" or "Elvis on black velvet" work,) it's probably not worth much, but, if it's a nice enough painting to look at that you'd want to hang it on your wall, then it's worth cleaning up and framing and hanging it up. It will never bring a high price at an auction, but you will always have a nice picture "painted by my grandfather" hanging on your wall to give you pleasure. On the other hand, if your grandfather was Pablo Picasso...

The bound sets do have a number of photographs-- not likely all taken by researchers, but they are well-curated. There is also updated (ca. 1980s) information and background on most of the boats included. Another very nice feature of the bound volumes is the introductory sections which include the history of the HAMMS program as well as retrospectives by a number of people involved.  A very nice surprise is the artistic and full-color plates made by some of the researchers-- there's an entire "artwork" appendix in one of the volumes.  I haven't seen sets listed for $3,000 in recent years, but have for around half that; it's actually an incredible bargain when one considers ordering all the plans individually from the Smithsonian. 
 
Here's a jot I wrote about these Volumes recently, for any interested: 
 

The Historic American Merchant Marine Survey
 
In the midst of the Great Depression, the Works Progress Administration had many projects designed to employ workers laid off from various trades.  The short-lived Federal Project No. 6 employed shipwrights, marine surveyors, and naval architects to document ships and boats around the United States.  Despite its formal name (Historic American Merchant Marine Survey), many of the vessels surveyed were more common or anonymous than historic; a number of recreational craft and foreign-builds are also included.  During the year-and-a-half they were active (1936-1937), they recorded over 350 vessels.  Some consist of lines lifted from half-models in museums and shipyards, while others were on-site documentation of full-size vessels—some derelict, some still active.  The presentation consists of the common three-view scale drawing of a vessel’s lines, and often numerous pages of construction details, machinery details, and sail and rigging plans. 
 
These drawings, while available individually from the Smithsonian Institution for many years, had not been assembled into publication until 1983, when the Ayer Publishing Co. of New Hampshire turned these into a large seven volume set, complete with an introduction on the project, retrospectives by those involved, and new introductory information on each recorded vessel.  Further, the volumes include photographs of many vessels during documentation, as well as full-color and monochrome watercolor sketches made by the surveyors. The beauty of this edition is astonishing—and every drawing in it was hand inked by gifted experts, each with their own style, precision, and artfulness. The size—23-1/2” x 18-1/2” is a very worthy size for the quality of the illustrations, and many pages are foldouts. Very few libraries hold these volumes; I haven’t been able to find how many were printed.  According to WorldCat, only 11 sets are in U.S. Libraries, only 2 of which are on the West Coast.  
 
The range of documented watercraft is astounding.  Some of the older recorded vessels are from the 1820s, while others were just a few years old.  The survey includes dugout canoes from Nicaragua, a U.S. Revenue Cutter, sharpies, scows, schooners, barks, full-rigged iron ships, sponge fishing craft, tug boats, steamships, stern- and side-wheelers, and even two Polar exploration vessels (Peary’s S.S. Roosevelt, and what may be the only larger vessel from the survey still in existence: Roald Amundsen’s Gjöa).  Small inshore fishing craft of many designs and lineages are also represented.  
 
The West Coast is well represented for some areas, but in the Retrospective, a contributor expresses regret at not getting the program into and up the Columbia River.  Columbia River watercraft have since received attention and documentation, courtesy of the Historic American Engineering Record, established by the National Park Service in 1969.  The closest-to-Astoria vessel in the HAMMS set is the Steam Schooner Willapa, built in Raymond, Washington in 1908. The Willapa is masterfully recorded in over 17 sheets of drawings.  The volumes include a number of vessels of this type as well as other lumber carriers, including sailing vessels built in the Puget Sound—no doubt many serviced ports on the Columbia River. 
 
That this project was ever created is a bit of a miracle; its success is perhaps even more miraculous given the necessary organization and its brief existence.  At one point, the director of the project (Eric J. Steinlein) was faced with an overwhelming backlog of work the very day before the official termination of the project.  He penned a letter that afternoon beginning “Dear Mr. Roosevelt…” which bought them six more months to work. 
 
That this was the right project at the right time cannot be understated. A collapsed economy and widespread poverty spelled a quick end to many already aged wooden vessels. The age of working sail was effectively over, and steel was becoming the material of choice for smaller and smaller craft—eventually fiberglass would replace the smallest of wooden work boats. During the Great Depression, the older relics had not yet rotted completely away, and they were ripe for documentation.  These volumes provide a glimpse of what was—a diverse fleet no longer in existence, captured in its twilight. Also captured in these volumes are the mastery of draftsmen trained by hand, shipbuilders trained by eye, and the ever-pressing urgency of historical documentation. 
 
 

Here is the final product. The forward deck is done. The stanchions and railing  and mooring bollards will come later after all the deck work is done.

The next challenge is the ladders. Two for the bridge and three for the midships.
 
Thanks for looking.

With the disclaimer that I'm no chemist at all (My lab partner and I passed chem in high school by building a still and distilling the alcohol from cheap wine and passing it around the class so everybody could have a taste. The teacher was a bit of a lush and loved it!)...
 
Decent models should always be cased, but cases need a bit of ventilation so the air circulates some because whatever acids that are in the materials will otherwise collect and concentrate in the atmosphere of the case. I'm not sure how this happens, actually, but as I understand it, the less acid in a model's material, particularly a cased model, the better. I avoid acid like... well... acid.

To mount the blade, there must be a slot.  The slot has two outer wings of the table flying in the breeze and subject to flex.
58, 59, 60 look like they are involved with connecting the two outer wings so that the table is a single unit. 
To change a blade, they would have to be removed.  They are probably the easiest parts to go missing.
 
What you have there is a 3 wheel bandsaw. 
They are a nightmare. 
The blades do not want to track. 
They are difficult to mount.  They tend to slip off the wheels. 
For resawing, be prepared for a lot of frustration, heartache, and a low productivity with a lot of wedge slices instead of rectangles.
You may have to have replacement blades custom welded. 
Standard 3-4 tpi steel blades have way too much set.  They chew up the faces of a cut.
Wider blades will not assure better tracking.
 
Are you sure that the giftor is really a friend? 😉
 
For a bench top bandsaw,  I suspect that a 10" Rikon with the big motor - 1/2 HP - would be about a magnitude easier and more reliable.   If it is scroll cutting that will be its function, a Carter Stabilizer is worth what it costs and then some.
Lenox Diemaster2  1/4"  4 tip is my sweet spot.

Agreed. Manual shows on page 13 that they are for table alignment. If I only owned one power tool it would be a bandsaw.

Can't say for sure but it appears to be in the right place for an adjustable stop to level up the table. This would allow the table to be returned to true 90 degrees after being tilted. 

Yes. There were 300 copies printed in this run. Anybody who collects modeling books has surely lusted after one. They originally retailed around $3,000 each, but apparently didn't sell well at all at that price point! The few that were sold primarily went to well-endowed academic libraries, from what I've read. I've seen them offered for as little as a few hundred bucks in later years. I suspect these sets were purchased as investments which disappointed. The ads often tout them has having only having the plastic wrapping on one or two of the seven (I believe) volumes having been removed, which indicates to me the owner never looked at the whole set. I've seen photos of the bound set and have ordered individual HAMMS prints from the Smithsonian, but I've always wondered if the bound set includes all the photographic records on the survey subjects, copies of which the Smithsonian also sells, or just the drawings. This would be one set that cries out to be digitized in CD or thumb drive format for on-screen viewing and printing of plans on a large format printer. I doubt that will ever happen, though. The HAMMS and similar collections are probably big profit generators (relatively speaking) for the Smithsonian Institution.
