A Stevens 330, or 331. Could even be an orig Model 311 (which came and then went away in this style of striker fired mechanism).
They made a Riverside marked model (315?) on this action also.
Several House Branded guns built ono this striker action.
Used from just before WW1 to about '30 or '31 I believe.
The Pat. date on the side of the frame ID's the mechanism as Stevens striker fired (no internal hammers) and one piece (no bottom trigger plate) cast steel frame. They called it a one piece hollow cast frame.
Used from just before WW1 to about '30 or '31 I believe.
This design was changed to the internal hammer style in the early 30's.
The 311 reappeared but as the Springfield 311 IIRC using this action style.
The Model 335 is slightly earlier Stevens line. The action has a bottom plate to the action like most common SxS actions. The side to bottom edges of the frame are rather squared off in profile. That feature looks a lot like those of a Win21.
They made some nice SxS's on that line including engraved and stocked in European walnut.
The striker fired guns usually get rust and or dried lube in the spring mechanism and the pins slow down.
Sometimes the strikers are bent in a poor attempt to repair or remove them. Then they slow down and don't have enough energy to fire the gun.
Sometimes one or both won't stay cocked if the sear edges in the striker guide rods wears over.
Then when you open the gun it retracts the striker(s), but they then just follow right back down again as the gun is closed and you get nothing with a pull of the trigger(s).
They are kind of cranky to disassemble & re-assemble. Those mainsprings & strikers want to take a ride on you when removing them. But other than that they are a pretty simple action. Lots of fabricated parts of bent sheet steel in there, peened over pins,,stuff like that.
