Here's the weird one for me. The insert(thimble) stuck on this pin, but the top stayed. When I unscrewed it, I noticed that the void under it was packed full of fiberglass insulation. I learned something today. Now I need to search the rest of the line, cause I know there's one out there with JUN 2 1913, and I would LOVE to have a nice piece of mud with my birthday on it. Thanks for looking.
