Hmmm... this brings up the whole question of where, exactly, were wire wheels installed? The original bill of sale for my 1957 small mouth TR3 is dated December 8, 1956, and is annotated that delivery was made in late March. So it took almost four months for the dealer to obtain a car with the colors and options the buyer specified, or to get one ordered from the factory and shipped to Massachusetts.
So I wonder, were the wire wheels installed at the factory, where they would have supposedly included the "factory original" knock-off hammer, or were the wire wheels installed by the distributor (the USA-based distributor) where they may have come up with whatever was handy for a knock-off hammer?
