Here's an antique tin toy currently for sale on eBay. The toy depicts a boy feeding a chicken -- a very big chicken. The actual toy is 7" long and 4" high. If we were to scale the boy up to anything like that of a real human, the chicken would be the size of a Velociraptor (actually, more like its larger cousin, Deinonychus).
Despite the dubious scale, it's still a wonderful toy. Made in prior to the WWI in Japan, the toy was meant to compete with the famous German toy manufacturer, Lehmann. As you can see in the video, when set running, the chicken pecks at the bird pan as if feeding. According to the description, the toy's mechanism utilizes a verge escapement. It certainly appears to be using an escapement to measure out the pace of the action, but the picture of the bottom of the toy doesn't quite show the mechanism in question.
The toy is in beautiful shape for its age. Tin toys took a lot of abuse. Just imagine how many times this has been used in the last 100 years! Here is where you can get all the details or bid on this antique Japanese tin toy of a boy feeding a chicken.
