I recently purchased a late 1940s Buescher Big B alto that included this mouthpiece in the case.
It has no markings at all. The mouthpiece looks like it was lightly used, which would also go along with the condition of the saxophone.
I thought that it may have been a Buescher mouthpiece that came with the saxophone when originally purchased, but it doesn't look like any of the ones I've seen online.
The ligature that came with the mouthpiece is also unmarked, but looks like a vintage berg larsen. It also looks like it has been used considerably.
I have found a couple images on the internet that look very similar, but not exact.
The first is identified as a "Woodwind Co. New York, Steel Ebonite B5* baritone" listed on the old worldwidesax.com website.
The other is identified as "Abbot Alto Saxophone Mouthpiece RR" on Roberto's Winds (https://www.robertoswinds.com/products/abbot-alto-saxophone-mouthpiece-rr)
Anyone have any thoughts?
EDIT:
I took out a magnifying glass and I am now able to see some light markings. The only one at this point that I can discern is the word FRANCE on the side of the mouthpiece by the table.
