We decided to combine into a single timeline reference to better understand the instrument serial numbers vs. Been playing Bach s for over 55 years, own many b flat trumpets, the oldest being a model 67 serial 9659, model 98/98 serial 98976, 77* 759675 they are solid performers that stand the test of time. It is one of the first hand full of Mercury trumpets that came out of the factory in April of 6996 using bachs own material.

All the ones before used those Import valve bodies.
