I received one for Christmas from my father, who got it from his uncle back in the '50s. It was wrapped in a rotten old cloth and hadn't been cleaned in years, but I took it down to the last screw and gave her a good scrubbing. It cleaned up well, but I still need to shoot it. A cross reference shows it is a Mossberg Model 75B: http://home.epix.net/~damguy/mossberg_shotgun_Moss-cross.htm I don't know what it's worth. Mine's worth alot to me.

The collector value can only be assessed by a visual inspection & evaluation. Old Winchesters are very much like old classic automobiles... the graded condition and factory originality are the key factors in determining what they are truly worth. Bert H.

your savage model 311 double barrel is valued at between 130-275 dollars depending on condition.You can add 20% to those fiqures because it is a 20ga model.
You are about right on the date of manufacture. It was made for Folsum Sporting Goods either by Crescent Firearms or a Belgian firm and probably had 28-30 inch barrels before someone cut it down and added the Wells Fargo stamp. Despite what you've seen in the movies, a stagecoach shotgun would have full-length barrels. It would also have been 12 or 10 gauge.
