Vincent Bach Trumpet Leadpipes The first Bach trumpet has a number 2 (sn #14) leadpipe. I have seen different leadpipes on early New York Bach's like 2, 4, 6, 7 and 9 (4 and 7 on Bb M bore) later on 6 and 7 became more standard. For example on the Vintage Limited Edition 198 it has a 6 leadpipe. At the end of the Bronx period and the beginning of the Mt. Vernon period the leadpipes (25,43) and bells (37,38 (M) and 43,72) became more the standard. The difficulty is that the markings on the bell and receiver are not there so it's only possible to verify the exact leadpipe and bell by shop cards. This list of lead pipes summarizes the different leadpipe components in a simple list for easier comparisons. We are always looking for your feedback on your experiences with each of the bell, and leadpipe combinations. Email us through our "contact us" link on the header of each page.
