Wow, what an ID! It reminds me of an older guy I met years ago, My dad was an archaeologist for the Forest service so he got to meet lots of interesting old Vermonters (the state where I grew up) through his job. One summer dad and his boss Dave set up a week long "archaeology camp" for some local kids. They located a site, the land where a lumber baron built his mills and charcoal kilns, got permission to excavate it, and then brought all us kids up to do a week long archaeological dig. I remember we only found one coin, an indian head penny, but boy were we excited about it! They got a few local historians to come help us determine what we found, including this old guy previously mentioned. This guy could take a look at just about anything that we found and ID it, it was absolutely incredible. This is actually the same guy who ID'd the Model T wrench that I mentioned in my previous post, that's what reminded me of this.
Anyways, long story short, it's always amazing to meet people who have so much knowledge about historical objects, I feel like it's a disappearing skill that will be missed once it's too late. Good job everyone, glad some people are keeping it alive.
