3D Naval Guns 1850s ~ 1870s

[Lieste]

Douglas 1855 has some drawings of a pivot and a (very flat) block trail carriage for the 1842 no1.
In line at art 221

Also, try Lafay at BNF https://gallica.bnf.fr/ark:/12148/bpt6k9737980n/f789.item.r=lafay artillerie

Several different block trail carriages and also pivots for the obusiers. (Also the later mod of the truck carriages, braque fixee for the caronade, embarkations etc) In the end plates.

The Lafay link goes to the same carriage that I made, which I'm thinking is for a smaller gun, abiet very similarly shaped; but Douglas shows...

which specifically says is for the gun I'm doing, so I think I'm going that route.

 

Thank you very much Lieste, for pointing out a document I already had

That one is in Lafay too - a few plates after the 'taller' 1840 no1 carriage. Plt 17 lower

I found I could download the PDF of Lafay, so now I have a reference if another French gun shows up on my inbox   

[Lieste]

The PDF is a lower res than the online 'zoom-view' where you can easily read dimensioning etc. I have offline copies, but will go onto BNF to get a better view of plates (and some tables). They have a variety of other texts as well, but Lafay is one of the more and better illustrated. The online browsing can sometimes be a bit glitchy though. Being able to zoom at higher resolution is useful for an inset part of a larger plate, which can otherwise be obscure.

There is a plethora of French pattern instruments and gunner's materials in the plates too. Not sure how early these patterns would extend, as Lafay is c. 1848 with some last minute additions. Most should go back to the 1837 regulations (unless specifically dated after that)

I got this far on it before I had to do other things today and tomorrow.

Comparing the tube height to the sailor figure, this carriage is definitely a better match for the model it will be living on.
I'm modeling it in 1:36 scale, but I'm printing them in 1:100.  Besides what I print for my friend building the model, it'll get posted on Thingiverse when it's done

In particular - the anspect (levers) for this carriage type have a little roller allowing them to form a 'rear wheel' for when running the guns in or out. Those for truck carriages for earlier patterns of guns just bear the rounded end on the deck to shift the carriage about.

[Lieste]

The 'taller' block trail carriage is dimensioned as 989mm to the top of cheeks (526+323+140), while the 'longer, sleeker' one is a little over 940mm (890 +50 for the rise of the lower edge ahead of the truck -  it is 450mm above the breast). Both are for 22cm no1 guns of 1842, 1841 and for different vessels. I believe the taller carriage may be the standard 'tween decks' (lower battery) carriage, while the (very slightly) longer and lower one is intended for the spar deck of paddle steamers. As the model is a paddle steamer, this is likely to be the proper design, if not on a double pivot.
