David: The barrels show 12ga with 2 1/2" chambers (the 12-65) and may have possibly been reproved as required in Europe if it was shipped there or taken there by a G.I. I can't get the picture to zoom up enough to identify the marks for sure but I think them to be English. The serial and grade marking look like Parker which leads me to believe the other stuff is a re-proof. I don't see any Remington marks of any kind but I'm just learning like most of us. Lee.
