I am looking for the same thing. I have a J. Stevens model 54 in .410 that my grandfather left me and cannot find any info on this shotgun. It is bolt action with a cocking knob on the rear of the bolt. Any info would be appreciated.
Old gun catalogs, auction sites, gun shop, gun show
It is probably a Swiss Verterli c. 1870-80 ~41 cal. I'm told about $250. Google will bring up additional info.
Many Mauser rifles were converted into shotguns after WWI.
Blue Book of Gun Values, Standard Dictionary of Firearms.
Mauser k98 value $475
Stevens made a number of inexpensive bolt action utility rifles, including the Model 56, a 5 shot magazine repeater. Values range from @ $50 for one in poor but working condition, to @ $200 for one in excellent condition. I'm afraid that I can't provide any more info, since there is no collector's market for these guns.
Not nearly as much information as say, Google, or the NRA.
Original 1937-1939 Wards Western Field 20 Gauge Repeaters had no serial number or model number, may have had a stamped number located on the bottom of the barrel only seen by separating barrel from stock. The bolt-action gun included a 26 inch tapered barrel, full choke and fired 2 1/2 or 2 3/4 inch 20ga shells from a fixed three shot top loading magazine. Probably valued in the 150-200$ range depending on condition as there is not much of a market for bolt-actions anymore.
Sears didn't make guns - they sold guns marked "Sears" which were made for them by many different manufacturers. Most bolt action shotguns were made by Mossburg.
