One of the most popular toy motorcycles of the early 1950s was the Mac 700, which was Arnold's new spin on it's 8-inch flat-twin Zündapp. Following the second world war, Karl Arnold was under American control, and their toys were stamped with "Made in US Zone Germany." The 1950s version of the motorbike featured a civilian rider, without a helmet, with an expression that suggests he's bracing himself against the wind. When wound it has a clever progressive action. At first Mac remains seated on the bike with the engine running, then he gets off and stands beside it. He then remounts and rides in a circle, stops to dismount, stands beside the bike before getting back on and riding off again.
This is a great example with minimal paint damage.
