Record has no cat# on the labels, 500 CG23 / 500 CG8 are matrix numbers. Anyway record was unofficially listed as Gilt-Edge #504 in later distributor ads.
As per the other ad shown, the record was also once numbered as CG 22. Doing business with Gilt-Edge must have been a pain in the ass. It's a wonder that Cecil Gant got off to such a good start with this label as his platform.
