Jay, there are easy-to-use interior micrometers that aren't expensive. Decent Chinese ones can be purchased mail order from a company called ENCO (Atlanta and other warehouses). You would slip this device down your receiver and measure the inner diameter of the receiver just at the point that it ends and the mouthpipe starts. Then, you would nudge it in just a hair farther and measure the inner diameter of the small end of the mouthpipe. If a person's mouthpiece exterior and interior dimensions lined up with those mouthpipe and receiver dimensions - and fit nicely - I'd say that they were in business. If they didn't, the numbers are right there for one to make their own decisions.
I'm not sure that I want my mouthpiece and mouthpipe to necessarily conform to some industry standard.
