A week before Christmas I found one on eBay that looked pretty nice, was not too expensive (about $24 IIRC), claimed to be original and came from a dealer with near perfect feedback (lots of it).
The pin arrived the other day, I pulled it out and it looked like this:

The scan doesn't do it justice. It's shiny and just perfect. Flawless celluloid surface. I thought it was the nicest 40's era pin I'd ever owned. And then I turned it over. Again, flawless. And that's the problem.

So now I have a question in to the seller. He seems like a very nice guy, emailing me about sending the pin out after Christmas if it wasn't something I needed for a gift. And his feedback is almost perfect. I asked him if he was certain that the pin was an original and not a reproduction. And I was very polite about it. So I'll be interested in hearing what he has to say.
UPDATE:
I was contacted by the seller today (Monday) and he provided me with enough info and a backstory on his pins that I'm pretty sure the pin is original. Looks like I made a pretty good deal.
