Shires Leadpipe Mouthpiece Insertion Depth

[Trombola2112]

Do all the shire leapipe variants (such as long vs standard) have the same insertion depth? I recently noticed the one long pipe I have (B 2L) allows my mouthpiece to go in about 1/8-1/4 of a inch further (by my best measurement. It seems to play fine to my, but I am curious if that is normal or not.

I heard from Christan Griego on one of his recent videos that Shires is now making pipes similar to Yamaha bass pipes that eat up the shank of the mouthpiece. I think they deliberately make them that way. It's at the 3:50 ish mark:

They should all be the same, but it's hard to make them that way. They have some variation.

That's old information. Shires did that at the beginning but went to a more standard 1" Morse taper insertion many years ago.

And there is manufacturing variation. Sometimes it was more variation than I was comfortable with when I was working there, but I was not in charge of manufacturing or design. My sense is that they are more consistent recently.
