Great find Greg!
Question for you...& anyone else that has one of these rare pieces...does it fit snuggly & securely? When I've put mine on, it seems like you could wiggle it off if you really tried. I remember a few years back that some turd stole one off someone's Dime at the Eagle Rock meet.
I got a brand new NOS one and it fits snug like a bug in a rug.
