Robert,

I use google patents to look at the patents. The Allender conection is from Larry's patent book. I think he says that patent date shows up on some C grades. I'm curious if the other variations of Baker changes happened around the same time. I'm refering to the cocking mech, and barrel lug specifically. The earlier guns seem to have two studs from either side of the lug for stability, which seem absent on later guns. Do you suppose the change in the angle of the 'cocking rod' took place with the change in locks and lugs???
