YAMAHA Bobby Shew Jazz Trumpet Mouthpiece

This is a Bobby Shew Jazz mouthpiece.
It has been plated in green gold.

I am listing it because it hasn't been used recently.
Please understand that there are minor scratches.
According to the Yamaha catalog, the specifications are as follows:
Rim inner diameter: 16.85 mm
Throat diameter: 3.65 mm

Thank you.
