I'm going to go out on a limb here, but I have a feeling this is legit. Some really unexpected things have popped up in the past, things that nobody even thought existed. If it is real, I'm going to guess that it was produced for exhibition at military installations. Most likely during the holiday season of '78.

Also, looking at his previous auctions for the vintage Martin, he is encouraging local pickup. I think if that's the case, he shouldn't have a problem with someone picking up the film in person as well. Scammers don't usually meet you in person.

But I do agree with what has been said, the seller is not making things easy. He could be sitting on a small fortune and his responsiveness, or lack thereof, is mind boggling.

Oh, and that bingo ball auction may just make me rethink everything.
