There is a light tooth indentation on the beak which can easily be fixed by a mouthpiece patch. Take a close look at the shank, and you'll notice that there's no scroll design. I've had dozens of Short Shank mouthpieces and I've never seen one without this feature. Perhaps the scroll press wasn't working in the Selmer factory the day this one was made?
Regardless, the new owner will have an absolutely unique mouthpiece. This mouthpiece is fantastic for classical playing. It is very free blowing and one of the darker and richer short shanks that I've ever tried.
I invite you to try this mouthpiece risk free. The item "1950's Selmer Short Shank Alto Saxophone Mouthpiece From Mark VI" is in sale since Saturday, June 24, 2017.
