I have a 12 ga. Rev-O-Noc Shotgun that was my dads for many many years. Patterned after a Model 97 Winchester Pump
Krumui,
If you Google up 1898 Marlin pump shotguns you'll see that the Rev-O-Noc looks identical. Marlin produced these for Rev-O-Noc shotguns. I had a #1 SS trap, pan marked Rev-O- Noc and a year later found a pump 12 gauge with Rec-O-Noc marked on it. My brother has all my collector traps and the pump shotgun.
Great gun, with nice checkering on it. You're correct that the Rev-O-Noc (Marlin) is a copy of the Winchester 1897, which was invented and sold to Winchester by John Browning.
