    Who can explain this horn? C.G.Conn Ltd. Made in Elkhart Ind. is on the bell. The letter L is on the second valve casing as well as Patented Factory 4 in an emblem. The serial # is 123927.

    I think the additional tube changes the horn into a horn in the key of A vs Bb.

    I agree, either Bb/C or A/Bb. For Bb/C there would have to be another set of valve slides. Christine, the Connloyalist would have more info for sure!

    hey fellas.........
    Christine (the Conn loyalist) said because of its age it could be a cornet (if I understood her correctly). She said the 2 slides make it a high pitch/low pitch horn. But I don't know if that means the same as Bb/C, A/Bb, or Bb/C. It has a wonderful tone in spite of its terribly leaky valves. I paid $150.00 for it in a local pawn shop, and I'm trying to decide if I should have the valves worked on. What do yaall (southern speak) think?..........crow

    High Pitch References

    High pitch seems to have been the preserve of the Philharmonic Orchestra movement and subsequently military bands. Our earliest clear reference seems to be a London Philharmonic concert in 1846. Despite a number of attempts to rein it in, it continued until 1895, when, according to conductor Sir Henry Wood, a throat specialist Dr George Cathcart financed the series of Promenade concerts on the condition they be conducted at Diapason Normal (435). It seems a compromise of 439Hz (the predecessor to modern pitch) was actually adopted.

    The data point at 433Hz, 1820 has been included in the High Pitch series as a possible departure point for this pitch. Hopefully, further data might fill in the gaps between 1820 - 1846. Military bands battled on at 452 until 1927 when an amendment to the Kings Regulations adopted 439Hz.

    Wilmer,
    I hope I can find a mouthpiece that will put this horn in pitch with Bb/C. I'd like to have a horn that can do both. Am I thinking correctly?.........tom

    Bach has for many years offered a C/Bb trumpet. You should have no problem using one mouthpiece for both keys, but having the valve slides in the right place is paramount to good intonation.
