This single-cylinder air-cooled .60 size engine was machined from aluminum and steel bar stock and designed to burn methanol on spark ignition. The builder and date are unknown, but the engine was made in Germany. It is equipped with a commercial carburetor from Dynamic Models and a custom made timer assembly mounted in the back; the (battery and coil) ignition system is inside the base. Note the stippling on the crankcase was performed by hand.
