I found this document in the National Archives, "Record Group 45,, Office of Naval records and Library, Subject File, 1775-1910." Specifically in "Box Number 139", while researching my Johnston Blakeley biography. Since it looked kinda cool, I had a copy made. Good thing I did, because I don't believe such a document appears in print elsewhere.

 

The documents' full title is "Dimensions of Gun Furniture by Caliber and Length of the Gun, 1821-24." The authors name is not recorded.

 

It is very long, and I almost regret volunteering to transpose it here. But the information is very useful for ship modeling, especially in larger scales.

 

It is divided up separately for long-gun and carronades.

 

Although it is dated 1821-24, I believe it is applicable for all navies, plus or minus at least a generation, probably more. Note on the Staff Table below. They have assumed a length for a standard long gun of the period, but long guns vary greatly in length, and since the staff length is a function of the bore, the staff will be unique to that gun. (Example: There were long nine-pounders that vary in length from five feet long to nine feet long, and the staff must be long enough to push the charge all the way back).

 

I will be copying one page at a time, as time allows. Here it goes 

 

RAMMERS, LONG GUNS:

 

"Rammer Heads: The Same Diameter of the Shot. One and one half the diameter of the Bore of the piece in Length. To be made of seasoned oak. With a score to receive a copper [feruly ? [A Ferrule, perhaps? This is a metal ring or cap used to strengthen a slender wooden pole] on the end next to the staff, and another for a seizing.

Next page. This document is not bound, nor are the pages numbered. I am listing them in the order given to me twenty years ago. Since all the Gun's dimensions are listed together separately from the Carronade's, I will assume that this is still in some logical order.

 

SPONGE BLOCK, LONG GUN: [Note: NOT Sponge Bob!]

 

"Sponges, Blocks,

 

The same diameter of the shot of the caliber below the caliber [of the piece].

One and two thirds the diameter the diameter of the bore of the piece in length.

 

To be made of a poplar wood with a secret worms.

 

[i don't know what a 'secret worm' is, but the carronade's sponge block doesn't have one. Maybe he's a friend of Sponge Bob.]

SPIKES FOR TOMPIONS, LONG GUN:

[i'm not sure what this is ... Perhaps the tompion was hammered so hard in place to keep the water out, that they needed a chisel to remove it?]

 

 

"Spikes, for Tompions,

I suppose what they mean is that the point was square in section, like an old-fashioned ice pick. Makes sense if they use it to pierce the cartridge.

This could mean that the eye was welded closed.
