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 the Henry Rifle Barrel Company, the same “Henry” as referred to in the gun’s name. Original Henry parts are the rarest of all manufacturers. All have been checked for fit on an original British manufacture cocking indicator rod. We have fewer than ten Henry tumblers. 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.
