Chuck, you missed a great show yesterday. Lots of O gauge. As you know, I'm an HO guy. I really cleaned up; there was a dealer who didn't know what he had. The major scores included:
Tyco red-box-era PRR light-up caboose, still in box, looks unused, $5.
Mantua Western Maryland derrick kit in box, small detail parts still sealed in plastic bag, $10. (On the rare occasion that one of these shows up on eBay, it goes for at least $50.)
Varney Aerotrain dummy locomotive kit in box, unbuilt, $10. I would have paid $10 just for the box, with that gorgeous illustration.
