Vincent Bach was a rare combination of artist and engineer. He was constantly changing his mouthpiece designs until the mid 1960’s when they became more standardized.
The formalization of the 27 throat and backbore to cup letter (A=24, B=7, C= 10, etc.) created a standard for the mouthpiece making that is still used today. These standards are known today as the Classic Series.
