i am looking to see if anyone knows who made this hot air fan.

it has 12" blades, 1 1/2" power piston
the brass housing is 5 1/2" diameter
it has a counter weight on the main shaft.
the crank has a double offset for the power piston and displacer.
i can find no markings of any kind on it.

the first 3 pics are of my fan which is missing the rear cover.
the last pic is of a complete fan

Mary, you might try and shoot a PM to Lee Pederson. He has a bit of experiance with hot air fans. I am not sure if he replies to PMs or not but he is a sponsor here on the Stak.
