I recently aquired a Winchester 1897, it appears to be a riot shotgun with a poly choke installed the barrel is marked 12 ga. 2 3/4 CYL. It shows very minor wear, retains much of the blueing, and none of the screw heads appear to have ever been touched. S/N 928*** (@1947), with an E prefix just above.
The questions I have are what is the approx. worth and would it benefit to have the poly choke removed and a bead reinstalled.
