I don't have one to check, David, but I have a suggestion:
Take the male-threaded part of the mouthpiece to an auto parts store and someone there should have a thread pitch gauge to check it with. Check both standard and metric if you can (it will probably line up with one of each). A micrometer would also be handy to check the size of the threads, but it's pretty dicey checking male threads for size - it never seems to line up exactly, and I still haven't figured out if you measure the smallest diameter (between the threads) or the largest (on top of the threads).
Try to find one of the more "professional" parts houses that have full-timers that have been selling parts for a while - part-time college guys working at a chain store won't have their own thread gauge, but old-timer pros will.
