B-25 MItchell Bomber Wright R-2600 Radial Engine Stromberg Carburetor Mini Piston Keychain

This is a very rare and unique opportunity to own an authentic piece of aviation from the famous B-25 World War II Mitchell bomber airplane. After extensive research (see photos) of this mini piston part #394275 we have discovered it came out of a 1930's/1940's PR-48A4 Bendix Stromberg Injection Carburetor from a Wright R-2600 Radial Engine that powered the famous B-25 Mitchell Bomber in World War II. Piston head is 1 inch in diameter and 5/8 inches tall (not including pump arm). Comes complete with 32mm stainless steel split ring. Very limited piece. A fantastic conversation starter.
