Roger -

I have been wondering about measurement of mouthpieces for some time. In
your schedule for the M13, the tip opening seems clear enough (are these
100th's of a mm) and I BELIEVE the other 4 numbers are distances back along
the curve to the point of insertion of certain thickness feeler gauges
between the mouthpiece and a flat plate, but I neither know the thickness of
these gauges nor the units of measurement (except that they can't be 100ths
of mm or the first one would require a microscope to observe.)

Since I know you are "into" this subject at the present, could you tell us
what these numbers measure. I suspect I am not the only person who is both
ignorant and interested.
