I finally got around to running my big reproduction Maerklin duplex. In this video the engine is used to power an AHI toy workshop made ca. 1960, and a Maerklin powered hammer toy No. 4366 ca. 1929. The engine is running on compressed air. The AHI workshop is identical to the one I received as a Christmas gift in 1960. This workshop is in mint condition and has very little zincpest. The hammer toy is a recent acquisition ex-Germany.
