Joe, this was my thought too. The image sure looks like hot water heaters. I searched extensively, and I couldn't find any token like this one though. Can anyone point me in the right direction?
Okay this area of Rochester, NY has yielded a decent amount of 1940's coin. The company could have been a local company, or from another city. The token could be 40's, but I'm not sure. These are only clues. Thanks again for looking.
