Hi I have a part compleated Milhome Models SR Unrebuilt Merchamt Navy white metal Kit that needs an electric motor. I bought this some time ago (around 30 years) but never got around to finding a suitable motor. If memory serves me correctly at the time the Bulldog motor was a suitable candidate but after having searched for a similar motor I am at a loss as to how to proceed. There are no wheels in the kit only brass plates that are used to simulate the Bulllied wheels. So not knowing much about the moddeling scene presenyly I am a little lost. Any help would be gratefully received.
