I have a beauty of a Greene carbine lockplate. She just arrived this afternoon. It has such a short half-cock. What I can't figure out is how the one free arm(?) in the back is supposed to operate. I figure that it's somehow supposed to interact with the front trigger such that when the trigger is pulled/held the second spring is released from the Maynard cog back, thereby allowing the soldier to advance the primer tape up the little channel so that the next time the hammer is full cocked, the primer advances all the way to the point where it will ignite between the nipple and hammer.
Please look at the pics I found online from a most generous poster. Bet very few have seen the stock behind the lockplate. Looking for a Greene person to clarify what's in the two write-up pics.
Also, would anyone have proper names for all the parts on the backside of the lockplate? I can tell where the sear is, and the tumbler, but all the others I'd like some education, or a diagram with that stuff.
