Model for the Polish automotive mechanical school. It is a model from the 1960s, a cross-section of a 2-stroke engine. Fully working! This is not a toy. A very rare thing. Dimensions: 39 / 20 / 14 cm Weight: 2.3 kg All the parts are moving. Works correctly. The absolutely best gift for every friend of old cars, engines, motorcycle or trucks, steam engines or tin toys. I invite you to bid, not only is it a piece of history, it is also unique because there are not many of them left.
