When I bought my YTS-23 it came with two mouthpieces. One was the regular 4C and the other is a complete mystery...but I like it. Is there any way to measure the MPC so I can at least know WHAT I like? I have all my dad's Sterrett machinist's calipers, etc.

Hold a rigid flat piece of material on the table that goes to the tip. Use the caliper to measure from the tip rail (towards the outter edge) to the flat piece of material. Do this in the center. That is more or less your tip opening. To be exact takes some practice but you will be able to ballpark it.

Or feeler gauges.

To at least get an idea, put each mouthpiece down on a mirror, side by side, and see if one looks more open. Compare the inner features to see if the unknown one differs from the 4C in the baffle area above the reed or in the throat area at the end of the window. Are there any markings at all on the piece?

No markings at all. I haven't been able to measure it yet but it does seem to have a larger tip opening , a higher baffle and from the external dimensions and looking down the bore, it seems bigger internally. Those are all just eyeball.

Interesting - might be a custom piece based on a student mouthpiece. Whatever, if it works for you....

Use the inside jaws of the calipers.
