This is from a kit put out by Brad Smith and is representative of the Bremen "Caloric" Hot Air engine. This one was build by a friend of mine who has passed away, and is now owned by a great hot air engine enthusiast in eastern Washington state. I have the kit, but much of this has to be fabricated by the builder.

UPDATE, JULY 2006. I SOLD MY CASTINGS KIT FOR THIS ENGINE TO ORRIN ISEMINGER. HE WILL BUILD THIS INTO A MUCH BETTER MODEL THAN I COULD EVER DREAM OF ......
