As always, another great photo Jay. The Trumbull Vanderpoel Co. was a manufacturer of electrical equipment. The building still stands and I've passed by it many times on motorcycle trips in this wonderfully scenic state of Connecticut. It's located at 931 Bantam Road, Bantam, CT. I'm looking at it now on Google Maps "street view" but I don't know how to, or if it's possible to download the picture from their site.
