It depends on the grade on how desirable they are. In old shape they appear to be going for about 325-375 I used to buy them all day long for 250. Now this is for the standard ones and being older pre 70's. I have a book that Ives all the info you would want on them but I moved recently and I have not come across it again yet. 20ga is hardest to find model 37.
I have a 37 20ga that I believe is around a 1958 that was my Grandpas. Great for shooting clays. I don't get it out that often though. I would love to find a deal on a 12ga sometime.
First shotgun I bought myself as a kid was a Model 37 12 gauge (I think I paid 75 bucks for it back then). I loved that gun, and especially the "slam fire" feature. It was stolen when my house was broken into when I was in my 20's and I finally got another one a couple of years ago. I also put a Limbsaver on it because as JStang314 said, they will beat you up being such a lightweight gun. I'd like to have one in 20 gauge someday too.
I'd like to have a 20 just because it would be a little more pleasant to shoot clays with I think. I only have one 20 gauge and I enjoy shooting it.1st that sucks the big one to lose a gun like that... Sorry about that.. A violation that I am sure still burns.. Why do you want a 20 Ga... ?????
And I would like to try that Slam fire feature.. Be just like those guys in the Wild Bunch... I'll play Crazy Lee
I have a 16 & a 20. Neither will ever be for sale
I really need to do the research and find the date on mine. I know it was purchased in 57-58 but no idea on when it was made.
