Alan Jackson :

"The Talkin' Song Repair Blues »
and
« Meat and Potato Man »

Maybe these two songs are related with what you are looking for ???

I haven’t your level in trumpet playing but have already five implants inside my mouth... and never had any problem with them! After each surgery one week without any playing followed by one week of gradual recovery and voila…

Yes I remember Urban Sax. They were fully dressed in white. For October 6 in Aubervilliers I suggest the yellow jackets.

Here is the u(l)timate answer:

@BigDub
On this Chinese clone exactly as on the original Schilke P5-4, the water key is fitted upside down. And I understood why: when you quickly remove the slide you avoid hitting the edge of the bell.

Just out of curiosity, I wonder why nobody mentions here the possibility of using a cornet mouthpiece, with adapter.
I am not a wonderful example of a picc player, but I know several (far better than me!) picc players using this combo.
So I bought a Chinese (cheap but suitable for my use) clone of P5-4. Having tried all my trumpet mouthpieces (I have a bunch of them!) even my Monettes (not the AP or BP that I haven't) I finally found the best for me: a Selmer #2 cornet mouthpiece that I have since ... more than half a century...
