Dear Reg Smith,  You were absolutely correct in your assumptions.
I should have mentioned that the disks were of course re sales by Ruth
Bornand.  The labels were put there by Ruth.  Had I taken the time to
pull the disks, to find those with Ruth's initials on them, I would
not have sent out erroneous information. I was working from defective
gray matter.  :-) 

The initials on her disks were not, in fact, RMB but her initials,
RCB.  Some of the disks, written in a fucia magic marker, bear this
three-letter underlined initial while others are marked RC Bornand.

The only remains of a 1/2" x 3-1/4" paper label is the glue residue
from it.  The last remaining, bronze metallic tape with black
lettering, bears the following information;

  Line 1:  Bornand
  Line 2:  Music Boix Specialists
  Line 3:  139 4th Ave Pelham, NY

Ruth placed these labels beneath the disk title to the left of the
elongated stop hole on the right side of the disk.

I hope this info helps.
