T-Breech block

T-block which uses a lever rotating locking cam in order to lock the breech and barrel. It was originally designed by the French gunsmith LeFaucheux and patented in 1834. This type of locking system was common in France and Belgium during the 1830-1900’s and often found in shotguns and some rifles from that era. Only a few examples were used in German Scheibenpistols.Many variations exist such as the Roux- and Stevens lock.
