This is a very rare and interesting piece of bach history. In 1939, Vincent bach decided to make a "student" model trumpet. THIS IS STILL A PROFESSIONAL QUALITY HORN! He wanted to keep the cost down, so he imported the valve blocks instead of using his own. He imported 375 of these, although we don't know exactly who from- they are most likely German in origin. I can assure you, they are quality valves. These 375 horns are also the only ones bach made in this particular bore size, which is .446, a small/medium bore by today's standards. The bell is a real bach new york bell, however adding another layer to the mystery of these horns he decided to use the bell most bach cornets had on them at the time, mandrel #106. There are no large dents or dings on the horn, and no signs of bell repair. At some point the braces have been resoldered but other than that this is a very good example of an early piece of bach history; only 375 made! Raw brass, nickel valves in great shape, has a quick change to A slide stopper. I would describe the sound as velvety; nice and warm but csn really light up if you push it. Perfect for chamber work and smaller ensembles. Now is your chance to own a piece of bach history! Note: the serial numbers on these 375 mercury models were out of order. They came roughly at about the 4000 mark but they are numbers 10000-10375. I have a copy of the bach shop card to verify the age. asking $1,100, Or a possible trade for another older bach, although preferably a large bore. Email me at [email protected] for pictures.
