I hope my fellow SOTW members will help me out.
Im trying to assemble a list of M.C. Gregory mouthpiece serial numbers. This includes Model A, Model B, Los Angeles Resin, Master by Gregory Early Series, Master Late Series, Reloplex, and Simpson. Gale is not included because AFAIK they didn't have serial numbers .
The difference between "Early" and "Late" Master models is described below, or you can visit Theo Wanne's page for a visual here:
If you own an M.C. Gregory Id appreciate adding its serial number to the list.
Model of piece: Model A, Early Master, Late Master, etc.
[Master Series Early (has brass ring positioned slightly above the end of the shank)]
[Master Series Late (has brass ring positioned flush with end of shank)]
Type of piece: Alto, Tenor, Soprano, Baritone, Clarinet
Size of piece: 5A 18, 4A 20, 6 18, 5A 18M etc.
Ex. Model A, 4A 18 Tenor #1172 (mine)
Ive accumulated around 80 serial numbers so far by scouring the SOTW archives, eBay sales, Saxophone site museums, and dealers like SaxQuest, Tenor Madness, etc. In the end, its to get a better picture of quantity and type of Gregory mouthpieces produced to add to the M.C. Gregory database. The results will be posted on SOTW for any who are interested.
