Helped need identifying a gun-maker, possibly French

[dana_w]

I could use some help identifying the maker of a pair of flintlock pistols. They look French to me. The barrel and lock-plate are marked “Goyel A Brest”, but a lower cased “a” is used on the lock plate. Could this mean Goyel in Brest? I know there can be great variation in the spelling for surnames.

Thanks!
