    It would be most valuable to all Bach Loyalists if we knew what the last serial number was just before the strike. I am sure those Bach instruments put together by the original craftsman were the quality horns. It is furthermore important for those who may purchase one of these newer ones to know that were not made by the original craftsman. On the used market they should not demand more.

    It seems that instruments made in the early seventies were stamped ELKHART IND. At some point they changed that to ELKHART IN. Does anyone know at what time this was changed? It might help in dating instruments from that era.

    Hi,
    I own a Bach Stradivarius Model 4 New York trombone which has the number 128 stamped on the slide as well as on the bell. On the slide the 128 is where normally the serial number is located, on the bell it’s where the bell model on later model can be found. According to this website Model 4 was introduced in 1935 and according to the serial number chart 1935 correspond to serial 400 while serial 128 would more correspond to 1929/30. Does anyone has more information?

    Kind regards, Dirk

    Does anyone know what the letters HGM signify on the bell of a Bach 42 Tenor trombone with F attachment? H seems to indicate ‘heavy bell’, G seems to indicate Gold Brass Bell, but WHAT, for goodness sake does the M stand for??? RSVP

      The M stands for open throat bell. Not sure why M was chosen but that’s what it means. The throat entrance to the bell is larger than typical; the diameter reached in the bell end of the tuning slide is larger. My guess is if you took that tuning slide and tried to put it into another 42 bell, it would be too large.

      The “M” likely means it has a modified bore. In some way it is different from the original. For example, one or both slide bored has a different size, thus modified.

    Is it correct to assume that the serial number on the slide is used to date the horn (not the number on the F-valve body)?
    Thanks.

    I was wondering if someone can help me out with this. I have a BACH Stradivarius 16 Trombone Serial #4732
    By the serial number chart on the page here, it seems like it would have been made in the late 1950’s but as I look further I see that Production started in Elkhart, IN in 1965. There is an Elkhart stamp on the horn. So, when was this bone actually made?
