This engine was completely taken apart, cleaned and checked and found to be in excellent condition. A rotary two cylinder engine, fuel injected into chamber by air pressure. Gas and oil mixed as in two cycle. The two pistons are opposed of each other, firing occurs every cycle. To start, air had to be pumped in by hand pump, then two small air pumps operating from engine were to keep pressure up. The ignition was put on as a test, to see if it would run. It was found without ignition on it. I did get a few explosions out of it. For practical use, didn't seem to have been too much of a success. One thing for sure, the American or German in genuity is sure found in it. The workmanship of long ago is amazing. This is what I think the man or men had in mind building this engine. A small rotary engine, yet simple, just how far they succeeded, anybody can guess. As far as name or patent or the like, I found none. It was a great experience for me and enjoyed every bit of it. Hope all of you enjoy this bit of yesteryear.

I am a relative newcomer to the gas engine game, having been at it only a little over a year, consequently I am not familiar with some of the even more popular kinds of engines.

I was fortunate however, to find this engine very close to home and would like very much to know what kind it is. It has a 5?' bore and 12' stroke. The fly wheels are 36 inches in diameter with a 3 inch face. It had an igniter at one time, but has been converted to run with a spark plug. If anyone has the parts, I would like to replace the ignition system to its original form.

I have a couple of crumb-crunchers, ages 6 and 8 who are co-owners of this engine with me.
