this was made either 1988 or 1989.
I believe that this series of shotgun was made starting in the 1990,s and made up to about 2005.
Just sold one for $750.00/ like new
Blue Book of Gun Values will help.
A Fox shotgun double barrel B-SE Series H is valued at $599 in good condition. It has a 26 inch barrel and a 2 3.4 inch chamber.
They came in various barrel lengths and choke combinations. If it is not marked on the side of the barrel, you will have to pattern the shotgun to determine the choke
You will have to contact Savage directly for the answer to your question.I beleive that the serial numbers to the Stevens model 311 side by side shotgun are not in the public domain.I can say that the model 311 was discontinued in the year 1989.
$ 300-$500 if it is Police model with 18" Barrel, in good shape...I got one...
A fully functional double barrel should bring $150-$250 depending on the condition. Less for one that is only useful as a tent peg, and a little more for one in like-new condition.
Try Numrich gun parts corp.or gun broker.com under shotgun parts.
it was made in or around 1972
Forerunner of the 5100 series which evolved into the Savage/Stevens 311. Stevens made a LOT of double-shotguns with varying designs over the years. Depending on condition, yours would bring $200-$350 at retail. sales@countrygunsmith.net
The Model 311 is essentially the same as the Model 5100 which was identical to the Model 5000 which was really no different than the double barrel shotguns being produced by Crescent Fire Arms before that company was bought by Stevens.
