In 1926 Buescher Band Instrument Company was joined with the Elkhart Band Instrument Company (some claim that Buescher was bought by Elkhart Band Instrument), a company founded two years previously by Beardsley with Conn's Carl Greenleaf as secretary-treasurer. This can lead to what we call transitional models, which have some new and some old features. The production of old and new models can overlap, or in some cases features of a new model appear on the later batch of the previous model.Sometimes a company may hold back a batch of instruments and then release them a couple of years later.Although the dates in these charts are reasonably accurate, there may be some discrepancies for various reasons. Go to and check pics of various Conns so you know your forms, or you may end up paying 6M prices for a Mexiconn.Selmer SBA Alto What Can Serial Numbers Tell Me? The main thing you learn from serial numbers is the age of the instrument of course. You'll see a NWII or 6M on eBay occasionally listed as a late 60s horn because someone consulted the serial number chart and misinterpreted it.Īs Bruce says, it's best to have a pic of the horn. "M"-prefaced horns from the 20s-30s have 6 digits after the M. I'm not certain of this, but I believe that an "M"-prefaced serial number from this vintage will only have 5 digits. The Ms you have to be careful of are the ones in the 60s.Conn ran out of serial numbers and started putting letters in front of them in the late 50s or early 60s.starting with "C". BTW, officially, even NWIIs were listed as "6M" in Conn's catalogs, even though the 6M stamp didn't appear until after the Conn transitional period. As Bruce stated, the "M" stands for saxophone. Not all NWIIs have an M in front of the serial number. There were 2 sets of Conn models that had M prefacing the serial number, and this often a source of confusion.Ĭonn started putting "M" before the serial numbers during the New Wonder II (Chu Berry) line in the 20s.
