Is that the Yahoo group for the Old Time Radio Researchers? Also try the Facebook group; that's where a lot of the action happens these days...but I'm afraid if anybody had a copy of the show, it would have shown up in the normal places by now.
Your best bet is the Rich Conaty collection...but I know Rich didn't have many of those 180-or-so shows dubbed. He couldn't play them, at all, which is why I was doing some for him before he died. And as I've said, I've yet to find out what actually happened to all those discs after Rich died a few years ago.
The discs, themselves, are Victor Home Recording Discs, and take a very wide stylus to play them. Even playback with a 2.5 mil 78-style stylus will probably produce just silence. I used a 5.0 mil on the ones I did, with good results.
