The Marx No. 41 tank is quite popular among collectors and was included in several of their playsets. My example is kind of a hybrid. It appears someone had replaced the turret on it because it's slightly mis-matched in color. The turret is a lighter color than the body, but overall it's still a nice piece. I had a nicer piece in my old Marx Navarone playset but then sold the set off. oh well. There were at least two actual color variations: the darker green shown here and a lighter olive drab color (shown along with other accessories in the Marx Giant Navarone set below). The tank measures 6" (15.24cm) L from barrel tip to back while the body measures 5 1/4" (13.33cm) L x 2 5/8" (6.66cm) w x 2 1/8" (5.39) H. Enjoy! Opa Fritz and Oma Bettina
Here's a No. 41 tank (to the upper right of the' beach') on this Navarone playset.
