Stevens also further modified the design when they introduced the streamlined Model 620 in 1927. Under Savage ownership, Model 520 production continued until 1939 when it was replaced by the Model 520A which ended production in 1948. After the war, Stevens was sold to Savage Arms on 1 April 1920 and full production of civilian firearms resumed. The company was renamed the 'J Stevens Arms Company' on 1 July 1916 and New England Westinghouse used their manufacturing facility in Chicopee Falls, MA to produce Mosin-Nagant rifles under contract for the Russian Czar during World War I. Stevens was sold to New England Westinghouse on and production of civilian firearms was greatly reduced.

The Stevens Model 520 was a pump-actionshotgun developed by John Browning and originally manufactured by the J Stevens Arms & Tool Company between 19. Stevens Arms Co/Savage Arms Co (1916-1955) Can anyone tell me if I'm in the right ball park or where I can get better information? Does anybody know when they made the model 335 with a serial number? The Browning patents may even help.Near as I can figure it was made between 19 but then I was told Stevens didn't start using serial numbers until 1948. I was hoping to find some gun smithing info before I tear it down, but can fumble my way thru with a camera if necessary. I'm afraid the surface rust is too deep in some areas to just hit with steel wool and rust remover.ĮDIT I don't mind getting parts made. There is always the option of just going back with a rust blue finish. this one has a ribbed barrel, so I think it's actually a 521. If the firing pin is broke and you still have it PM me, I might be able to help you out. They don't list a scheamtic for the 520 but they may have a source. Spray the wool with WD-40 then wipe the gun down until it feels smoother.Īs far as shematics you might try calling Numrich's. I can see there is some surface rust and the best way to take care of this is with som 000 steel wool and some WD-40. That is what gives it the brownish color. Most of the early firearms had what is called rust bluing.

I would not refinish it because it will loose any value it has.
