I happen to run across an old Lyman deerstalker in a gun shop today. It had all the brass stuff on it(looked alot like a T/C Hawken)and it also had double triggers. It was a 54 cal. but I could not find any twist info on the barrel. It was in pretty nice shape and I was wondering if anybody knew what the twist would be and about how much the gun was worth?? The shop was asking $400.
