Marx Battleground, Training Center, and Other Military Playset Pieces - Marx German Motorcycle with Removable Sidecar - Lt Gray SP

I'm not a motorcycle person, but I do know that one of the most commonly used cycle's of the German Wehrmacht during WWII was the Zundapp KS750 and so it seems reasonable that Marx used that as the basis for this nice combo. It measures: 2.25" (5.71cm) L x 2" (5.08cm) H  1.5" (3.81cm) W (with sidecar) or 0.75" (1.90cm) W (without sidecar).

The sidecar simply slides out from opening's in the motorcycle's frame.
