Table Notes

None of the mouthpieces tested were new. The 12C model designated as "old" was used by my father and is therefore presumed to predate the other 12C mentioned. All measurements were made to the limits of accuracy of the eqiupment used; more accurate devices might yield different measurements, but that would not affect the intent of the measurements. Persons with differing measurements or measurements of different mouthpieces are invited to send them to the author at xaxnar@aol.com, along with details about how they were obtained. No mouthpieces were injured or destroyed during the making of these measurements.
