This poor beast looks like it was a really nice build that fell on hard times, and finally to the Buzz basement. There were a bunch of blob solder added with liberal amounts of acid that was not cleaned off. The rear axle bearings and motor were locked up solid. Amazingly, the only parts that were replcaced were the bare B-can, pinion, and rear axle ball bearings. Copious amounts of Industrial strength applied after removing the extra brackets and about of a quarter of a pound of solder blobs. I formed a can to axle tube brace instead of the four that were removed. At the end of it all it came out pretty nice.
Is this some kind of production chassis, or a one-off?
