"Armstrong's DP 1" is embossed on the front heel, "MADE IN U.S.A." then a small circle with an uppercase A, then, "7 50" It's a clear glass insulator I purchased for a dollar back when my interests were more piqued in these. Once more my interests are blooming, and I know it's not special, but how often does one come across these and what year is it from? I moved it from the basement where it was holding the door from slamming. I know, you're thinking, "Hmmmm. Glass insulator to stop a door slamming it into an unforgiving concrete wall. Oh, great idea!" Well, they were built to last and I've never had an issue, no matter how hard my family members slam it. Forgive the low-quality pictures. I'm fairly sure it's a bit heavier than a standard Hemingray-42. The bottom was smooth. No teeth, no drips.
