Just made another post about double barrels.Got a chance to pick one up from a bud for about $200.00 or maybe $250.00.(going to get it anyway)It is a Stevens model 311D SxS,has double triggers.I think I would prefer a single trigger model but what the heck,I can get used to just about anything.It will shoot 2 3/4 or 3" I would think the gun is fairly old if not for the 3".It does not have any serial numbers,only proof marks.This gun is in excellent condition.My main question is how do I find out how it is choked? I did the dime thing and can't get one down either barrel way we always said that means full.Does anybody know the measurements for choke? I can measure them with my caliper but still need to know the dimensions.
Btw ya'll got any kind of ball park figure on how old it might be or the value.

Thanks again...........Swamp
