Hello all?

I found this forum while looking for some info on an old Savage 12 guage semi auto shotgun and it looks like it may be the right place for my questions.

I dint see any threads or sticky about model identification so I hope I am not asking something that has been covered a hundred times.

I have come into possession of a shotgun which I thought was a Savage 745B , but now believe may be a 720. I have looked online and find a lot of contradicting information. The gun is 12 gauge semi auto with engraving of a pheasant and brush on either side of it. The barrel is marked proof tested and the receiver also says "Three shot" on it.

Thanks
Chris
