I was looking around on flea-bay and saw some old magazines. I happen to remember a Gas Engine Magazine that I took a picture for, I looked some more and found it. Bought it for $5. I'll try to find the original photo for a better look at the engine. This was on newsprint so quality isn't very good. I took this in 1976 at a man's house about 20 miles from where I lived. He had about 100 old engines and this was one of his rarest. It's a 1907 Bauroth Bros. made in Springfield Ohio. 4 HP with 5 spoke flywheels. Hit and miss gas engine. Hard to believe this was 42 years ago. He passed away and all his engines were sold at auction. I just didn't have any money to buy one. Can't remember how they sold.
I'm still digging through boxes of photos trying to find the original plus many other pictures of his engines.
