Now here is one that you won’t see at your local gun show, a Blissett combination flintlock and percussion rifle.
This unique rifle features both a flintlock and percussion ignition system. A pivoting flash pan and percussion bolster are mounted on the lock ahead of the flintlock frizzen and spring assembly. The lower portion of the hammer is percussion and serves as the lower vise jaw for the upper flintlock mechanism. There is a thumb screw on the bottom of the flash pan/bolster which is used to lock the mechanism into place depending on which system you are using. The side of the flash pan is marked "PATENT". The lock and barrel are marked "F BLISSETT, LONDON”.
