Maytag Toy Racer was one of several hundred built by Maytag in the 30s/40s The sturdy built steel and aluminum cars were powered with 1 or 2 cylinder washing machine motors which offered poor performance. The motor, belt guard and engine covers were typically removed and replaced with a Briggs or similar motor. Therefore in addition to the fact that the cars are rare and valuable today the motors, belt guards and engine covers are even more scarce. I've fabbed 2 replica bodies and several belt guards and engine covers and have an order for a set now. They were Coca Cola red and white with a goose hood ornament.
Regarding the Russian cars, Packard and Studebaker merged in 1957. They sold all the tooling and stamping dies to Russia, where they continued to manufacture a "Russian" Packard, I think called Zil. It looked like the '56 Packard.
