European naval pistol?
 

Could you please help me with identification of this pistol? It is certainly European, and from the brass barel i presume is made for sea service. But which country an d what date? Is it a specific navy model or a private purchase?

Some naval small arms had brass barrels, however that was simply an alternative medium for gun barrels in this period & should not be taken as a 'sea service' attribution per se. I know of no navy who provided such elaborate pistols for their seamen, which were usually of very basic design; so it is a commercially produced pistol. The general features of this pistol, the straight lockplate, reinforced pan, etc place it, in my opinion, into the late 1700s & early 1800s.
The proof mark should be recognised by readers, is it a crown over K? Perhaps a close up of that will help provide which country.

The round foreend of the trigger guard and the style of the sideplate is particularly typical for French pistols of the second half of the 18th century. The lack of proofmarks clearly affirms this. It is certainly a navy pistol made upon a private order of a French officer of the mercantile marine or the navy.

Yes its French C 1770 but I wouldn't necessarily assume that the brass barrel and lock plate indicate a naval use. The cock is a working life replacement and this together with the extemporised barrel band suggests it's had a hard life somewhere out east.

Hello

I agree. Shortly after the cock is fired, the jaws screw will hit the frizzen at the top end. The upper jaw is too long, as is the screw. The band that holds the barrel does not correspond to the model
