Just bought an older Stevens 325C in 30-30. There is no seriel number or id number other than "Stevens 325C".

Gun shoots well, all things considered.

Where to find more information on these models?

Any spec sheets etc?

Ther bolt is very different than the other Stevens/Savages I've seen, what type is it?

The barrel appears to screw into the action with the same barrel nut set-up as a newer model, will a modern barrel thread into this action?

The sights are simmilar to those on a Marlin .22, are there any other/aftermarket iron sights I can use on this gun?

Thanks for any help, Matt.
