Old Wind up toys seem to be hot in today's markets. This type of wind up was produced in Germany most likely prewar (1930's). This particular wind up was brought in to the Sandusky Home and Garden show last weekend. The toy when wound would squeak and the bird would rock back and forth. The manufacturers name is on the side and it is marked made in Germany. This particular toy recently sold for $125.00 on Ebay.
Keep an eye out for old German or Japanese wind ups. The wind ups that were produced post war in Japan also have a great deal of interest from collectors. Wind ups with the original boxes will bring an additional premium on the pricing. The post war Japanese pieces usually come in brightly colored boxes and are inexpensively made.
