He used a little metal rod with a short angle (looked something like this >>> ______________________I ). He inserted it into the receiver until the little piece hit the leadpipe, then measured with a caliper how much of the rod went inside. Then he took that out and inserted my mouthpiece and made a mark on the shank to see how far it went in. Next, he measured that length, and found the difference between the two.

I've found this to be true, too. I've been able to get a decent sound from any 'piece I've put in my 188 -- it's a very forgiving horn. I've tried lots of mouthpieces, but the ones I've used with enough regularity to tell a difference in the sound and feel are the Miraphone TU-23 (C4), PT-48, G&W Bora (old style), and G&W Bayamo (old style). However, in light of some recent reeducation regarding my approach to my embouchure (my usual large aperture, forceful, manhandling of the horn vs. focusing on resonance resistance management at the mouthpiece and letting the room do the heavy lifting), I've noticed that the mouthpieces with thinner walls do much better at providing an even response from the top of the range to the basement.
Good luck in your search, and have fun with the mind-boggling number of different sounds you can get on your 188 with different mouthpieces!
