One of the oddities on display on my workshop shelves is this "OK" brand "Super 60" 1940s era spark ignition engine given to me by an acquaintance. A product of Herkimer Tool & Model Works, Herkimer, NY, it ran on either gasoline or glow fuel (a mixture of alcohol, castor oil, and nitromethane). From what I could find of this engine, they were cantankerous and not easy to keep running well. If one could keep it running, they produced a lot of torque from that big propeller. This one may have quit running before I was even born, as the crankshaft is seized and will barely turn by hand.

I spent an unreasonable part of my childhood trying to get the Cox .049 version of this to start. I can't see a brand on this one.

I spent a lot of time using Cox engines before I discovered electric power. I had Cox engines from .049 all the way through .15 displacement. They were all very loud. The model of the engine in my image is actually called "OK"; it's stamped on the crankcase, along with a patent number. This one has a displacement of .60, and would have had the capability of powering a model with a 5-6 foot wingspan.
 
I really don't know the story behind this shoe sizer. It has a 1940 date.
Found it in my mom's things after she passed away and it was too cool to toss.
Her sister married a man who owned a shoe repair business for years.
He was in the pacific during WW2. AndI think he was a high school friend with my mom and her sister.
He passed away years ago, but it is possible he was the source.
