I posted thid today in the relic forum. Decided to clean it up, and when I did, the front round piece of glass came off. There was a bunch of gray powder inside, and another piece of round glass under that. I put the powder back in (the best I could, and placed the glass back on top. That puppy is going back to the field I found it in. It might not be what I think it is, but I don't need any bad juju.
