Original Item: The tumbler cocks the firing pin and acts as sear. The cocking indicator rod acts as the pivot for the tumbler. These tumblers are British made and bear inspection stamps from RSAF Enfield. Most also have a very nice W.D. with broad arrow War Department property mark. All have been checked for fit on an original British manufacture cocking indicator rod.
This offering lets discriminating Martini owners upgrade this internal part to match the receiver manufacturer. Also, the tumbler is one of the parts most frequently requiring replacement, and since they won’t be around forever, now is a good time to get a spare.
