"... and doubtless a lot of old fossils (like me) who know what the kits are and would want the stuff have fallen off their perches in the intervening time."
I like that one, Ace.
I have a handful of Parts Packs that I picked up at Nassau hobby back in the mid-sixties. Paid a quarter each for 'em. The Fiat is in the pile. And no, they ain't for sale.
As Ace said, before the Permian Extinction everything was loose in the box and the box was taped shut. Tire marks would happen after the kit sat forgotten in the back of the shelf for a few years.
