The plates look very good with no indication of polishing. Case hardened. Top right barrel is stamped LC Smith 12GA Field FULTON, N.Y. U.S.A. Serial numbers all match. The butt pad is a Pacmeyer so I believe this has been replaced. I am concerned that the side plates were taken when the pad was replaced. With out the owner knowing. Otherwise why would they be removed. The plates are very well matched/fitted to the rest of the workings. Should the receiver have LC Smith stamped on it, there is only the serial number and Field on it.
