A Parker Bros. Pump Gun?

[J.B. Books]

Earlier this week I visited the Cody Firearms museum in Cody Wyoming. If you go prepare yourself for sensory overload as they claim to have 4200 guns in their collection. The guns in glass cases combined with poor lighting made taking good photographs near impossible. I pulled out a drawer in the P section of their Gun Library and ran into something I have never heard about, a Parker Bros. Redfield Pump Shotgun. It's a prototype and very plain. The museum said it is from the 1932 to 1940 era. Who can tell us more about it?
