I get 38 with a .0015" feeler, 28 with .005", 22 with a .010", 12 with a .024 and 5 with a .032".
Your mouthpiece is an outlier - even the P34 is longer than 31.5. If it came out of the factory that way, I wonder how many others like it were actually sold. I strongly doubt that it was produced while Gigliotti was still actively involved.
There was a series of facings that were applied to the Gigliotti mouthpieces apart from the P facings. The original facings had numbers - #2, #3, maybe #4 - and were different in length and tip from the P series (P or P34). They predated the P, which he evolved after the line was already in production. It wouldn't surprise me if the original "#2" facing was meant to be a 32 length. I think the Chedeville that was the original model may have been 32 or 34. I have an actual pre-production prototype (similar to the original #2) that is 34-28-22-11+-6 with a 1.02mm tip (.040+" on my taper gauge). But if your mouthpiece were one of those, it wouldn't be identified as a "P" facing. He was trying to develop something that would take a stronger reed and after a couple of years of experimenting arrived at 38 (19mm for non-Brand fans). The P34 was meant for players who liked the blank but not the 19mm curve.
A mystery!
