I'm always intrigued by kinescopes that escaped the G-T vaults decades ago and then somehow pop back up for collectors to find. The seller of that Make The Move pilot we got together to purchase so many years ago told me she got it at an estate sale somewhere in New England, and I'm convinced a G-T executive took it home with him at some point and neglected to return it.
Wouldn't mind some Secret episodes turning up that way. Besides the hundred or so cigarette episodes that Fremantle never showed us (and even those are trickling out) I figure there are 30 Secret episodes that are simply not in the archives.
