The height of the platform gives this machine away as a pre-war build. Some 4097/7s were built post-war but the engine platform is much lower. This nice example comes with a 3392 dynamo and a 3447 lamp. I cant see any mounting holes on the base for the lamp, as some lamps were attached by screws. The furnace door is missing its latch, and its evident that this engine was played with, but like most Marklins, it has held up admirably!
