Here’s another stamp from the Foxtown district in Detroit, on West Montcalm Street at the northeast corner of Montcalm and Park Avenue. It’s next to the Colony Club building (which faces Park).

I can’t tell you anything about Rayco Utility Inc. There’s a Rayco Utility Services based in Troy, but they seem to be a trucking company, so I’m not sure if it’s the same business or not.
