This is a Ryan & Watson flintlock spring-loaded 54 caliber bayonet pistol with a brass barrel. They were in Birmingham from 1780 to 1784. The mechanical function is very good and the brass trigger guard and final are nicely engraved. This has a 7 ¾” barrel and is 13” overall. The ramrod is a replacement, and the wood stock is not damaged or cracked and has only small light scratches.
