John, take a picture of one and place an ad in the classified section here and also at the other radio forum. Be sure to mention they also fit an RCA Radiola Senior (thanks Mike). You never know what someone has just laying around in a box, jar, or drawer. When the guy who bought Gary Schneider's business (PTOP) gets everything organized I'd be surprised if he doesn't have a bunch of them.
Buying a thread guage is a good idea also. At least one of my tap sets has one but it's limited to coarse and fine threads. I've been known to take a nut or screw into the nut and bolt section of my local hardware store to find what I needed. I recently wanted stainless license plate screws and took one into my ACE hardware and quickly determined it was metric and the size by trying a couple of nuts they had loose in the bins. Good luck!
