try www.shotgunworld.com if they don't have an answer there aint one. (good folks there, alot like this place) those folks live and breath shotguns.

The Model 50 standard was made from 1954-61. They made a standard, a field gun with vent rib barrel, Skeet gun, and Trap gun. All made during the same time frame.
