Do these still exist? From a Delco Remy publication circa 1960 from my high school auto mech class. High output generators available in 1960 cars and trucks. It seems one of these would be perfect for those wanting more output without losing the authenticity of a generator. Showing up to 55 amps from a 12 volt generator used in taxicabs, police cars, and others. Does anyone have experience with these? I don't want one but if one were available it might suit someone like the OP that wants the 'original generator look'.
Also shown is the "extra output AC generator" that uses the same mounting as the standard generator. A period correct alternator.
