Jan .... I truly look forward to the day when you have all of your SEoPA ephemera up on your website!

On another note, the later version of the Sun Motor, called the Sun Runner, that was black, had only a single flywheel and an enclosed crankcase, was also first made by Solar Engines of Phoenix Arizona, so there was a point in time when you could buy both or either of these potentially solar powered engines. When PM Research bought up the earlier company, they chose to only produce the later model Sun Runner, so the Sun Motor would appear to be exclusively a product of Solar Engines of Phoenix Az. as far as I know.
