In 40 years this is the first time I have seen a chassis like this. I saw it on ebay bought it because it was unique. Does anyone know who the manufacturer is(was)? I would guess it was made in the late 50’s. My guess is an Athearn drive after the rubber band and before the old one we all know and love? Notice the two horizontally offset “knobs” on the side of the fuel tank. They are the perfect alignment for an Athearn GP-9 body.
Any idea the years they were manufactured? Were they rare. Manufactured only a short time? I mean I’ve seen zillions of rubber band drives, but never this one.
