If you would be satisfied with a date within 10 years more or less, post all the markings exactly as they are written on the gun. If you need an exact date, go to the Savage Arms website and get the address of the Stevens Historian. If you send him $15 and the serial number, he may be able to tell you.
The information you seek is somtimes hard to find because these shotguns are listed as savage/stevens which infers that these guns were made by one company savage,which owned the stevens name along with it,s own.The model in question which is a stevens model 237 was made by savage/stevens in the years 1936-1943,with a total production of 16,000 guns made.
The Stevens Model 125, a 22 caliber Bolt-Action, Single-Shot rifle was manufactured between the years of 1898 and 1912 in Westfield, Massachusetts by The Stevens Arms Co.If you Have a Stevens Model 125 with Savage also on the barrel than you have a gun manufactured by The Savage Arms Co. and it would have been made after 1920 when Savage Arms purchased Stevens Arms.I have a Stevens Savage 22 bolt action single shot 22 rifle model 125 and have yet to find the date of manufacture for it. wwworth
J. Stevens. Made the Little Pet single shot .410. I own A little Pet, and several J. Stevens pre model 94 thin frame single shot 410s and can confirm this as Fact. I also belive that the Little Pet name was used on shotguns made by J Stevens for Sears. This information I have gotten from several different sources and have yet to confirm, but belive to be Fact.
