Help me identify this Parduba Trumpet Mouthpiece

[Hangfire112]

I had a family friend who left a good collection of mouthpieces to me after their father passed away. All of these are vintage pieces, including a gold plated vintage Rudy Muck 14M ( I am not familiar with this size), and some vintage Parduba mouthpieces.

One of these Parduba mouthpieces is giving me great difficulty in identifying. Having looked through their old catalogs, and scouring the internet, I have not been able to find ANYTHING so far on this mouthpiece.

It is labeled J. Parduba & Son NEW YORK and has the size stamping of *5* on the front. Oddly enough though, it has NO DOUBLE CUP, and is not marked with the double cup designation. The Cup of this mouthpiece is a standard bowl shape design, like a Bach.

Experts and gear maniacs of trumpethearald, lend me your collective expertise. What is this mouthpiece?

5* is a stock size. Perhaps it was modified and replated.

What is odd to me is that if it was modified, that means that they would have had to replace the metal missing from where the 2nd cup on the double-cup mouthpiece Pardubas is located, right?

Also worth noting, there is no Pat. NO that you would normally find stamped on Parduba mouthpieces.

If Parduba offered a standard cup at some point, that would explain this oddity. But as I stated earlier, I have not found any record of that product offering.

Thank you for your reply either way.

Parduba likely made custom mouthpieces along with the regular line of double cups.

I'd assume that Parduba made this in a size 5 as you found it because there is no patent number for his double cup design.
