Help with identifying model of Stevens s-s 20 ga.

[Scionti95]

Was gifted a very old Stevens 20 gauge double barrel shotgun. Cannot locate any model information. What is visible is Stevens name on left side above double triggers with a waterfowl in flight. 20 gauge is engraved top of one barrel. What appears to be serial numbers (H44861) are engraved when opening the shotgun.

Lots of pitting on the barrel and missing a top snap screw. Want to bring this old gal, that has been badly neglected, back to life. Identifying the model will assist greatly in locating the top snap screw and a couple of other things that need to be replaced. No good with posting pics, so hope this information is enough for the experts on this forum to get me headed in the right direction. Appreciate !!

Now that sounds like a Stevens model 330.

Does it have internal hammers and is the duck flying right behind the Stevens stamp on the side directly towards it?

Mad Dog:

That is it exactly. Internal hammers and duck flying right behind the Stevens inscription. You have made my day. I can now move forward in locating a couple of missing parts, screw on top snap lever and the grip plate. With the serial #'s I found, any approximate idea when it may have been produced.

This is going to be fun. Going to try and learn everything available on the Stevens Model 330.

Thank you again Mad Dog. It has been a journey trying to identify the Model and You made the difference.

The model 335 might use the same parts as well.
