well i hate to say it but i have no idea what the diffrence is. I am a recent collector of doubles but must admit my knowledge is very limited if any at all. I have decided to go a diffrent path than my father that collected winchester lever actions and have just gotten into doubles with some o/u like a winchester 96 and a 101 then the martin and jus recently purchased the davey. i was told buy my dealer that he belived it was scottish or english and around a 20's model. i just know i thought it was a good price for a starter piece everone has to start somewhere. and my pocketbook doesnt allow for a win 21 yet but it will. but any help from you all is greatly appreciated i just love these old guns. and i can not find to many people in there 20's that enjoy looking at them as much as i do.
