Minimal Wave Records

I’ve googled this a bit and come up with nothing.

Anyone here know which label or plant in America marked their records with a little “WM” stamp (much like the Minimal Wave logo).....or does anyone know an American lathe cutter with the initials “RS”.

Time period is early 80s of course, 83 to be exact.

I’ll post a scan soon.

Thanks any helpers :D

okay, as promised.

The “WM” appears before a 5 digit number which is also on the printed label. It’s in the format 41XXX.  The record is a “big hole” 45 too, from 1983.

Also, the “RS” is really tiny and off on its own on the record. My guess is the cutter’s initials.

:?:

The only two I can think of is “Modern World” records or “Monster Wax” records, but it’s just a guess because I don’t have more information about these labels.
