Vintage Penzel-Mueller Alto Saxophone Mouthpiece, marked "New York", new/unused

Description

This listing features a vintage PENZEL-MUELLER Alto Saxophone mouthpiece, marked "New York".  The mouthpiece appears brand new and unused with no scuffs, no marks, nor signs of wear nor use;  There is no Facing designation on the mouthpiece.  The overall length of this mouthpiece is approximately 3-3/4", measured from the tip to the bottom of the shank.
The mouthpiece does not come with any packaging, but will be shipped well protected from damaging or scuffing.
This mouthpiece was acquired from a older music store that was going out of business.  From what I have read, the Penzel-Mueller company made nice quality clarinets and saxophones and their respective mouthpieces until around 1950, at which time the company went out of business.  This mouthpiece apparently was in controlled storage for a number of years and has been well protected and preserved.
