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.

About Bach mouthpieces
The history of Bach starts with mouthpieces. A century ago, trumpet player Vincent Bach began experimenting with designs and manufacturing processes to replace a broken mouthpiece. Soon after, Vincent Bach's mouthpieces, and later his trumpets, set the standard for excellence.
We continue that standard today through constant innovation and dedication to the craft. In the Bach workshop, crafting a mouthpiece begins with innovative, yet classic designs and is then carved by a computer-numeric-controlled machine that shapes and cuts solid brass bars. Each step is precise within one ten-thousandth of an inch.
When selecting a Bach trumpet, cornet and fluegelhorn mouthpieces, a brass instrumentalist should choose one that allows the player to produce a solid, compact tone of large volume. A carefully selected Bach mouthpiece can help improve a player's embouchure, attack, tonguing, and endurance.
Because no two players have the same lip or tooth formation, what is perfect for one player may be entirely unsuitable for another. Bach produces thousands of different combinations of rims, cups and backbores so that each player can find the best mouthpiece for their individual embouchure.
