Vintage Custom Mouthpiece W/Illegible Markings (Lot #1432)

Description

This is a very interesting old mouthpiece with markings on the cup that are most eligible. I can make out a number five but that's about it. The rim is exceptionally smooth shank is very round there are some insertion Marks and some plating wear as well as a little bit of damage to the outside of the collar from what appears to be pliers although it is not severely significant. There is a very slight angled bend to the mouthpiece that I tried to capture in the fourth picture. this mouthpiece came out of a very large collection that I purchased a long time ago and that I have been just sitting on.
