Conn connstellation trumpet dating
Most were made post World War II possibly up to 1960.
If you see one of these horns and the owner is claiming they are from the 1920s or 1930s or before, then they are using the wrong serial number chart.
I am told the 80A has a duo bore or "expanding bore" main tuning slide: the top half is a #2 (0.468") bore, the bottom half is a #2½ (0.484") bore.
The lacquered main tuning slide on this otherwise silver plated instrument is not standard, it is a replacement of the original which was damaged.
If your Buescher Trumpet/Cornet bares an engraving of an ELK on the bell, please see the note below the serial number chart.
Features amazing electro d bell, top spring less crysteel valves, non corroding micro finish mouthpipe and scientific cali bore.
* The S prefix, while used until the mid-80s, was not always seen on serial numbers.
The Conn-Selmer resource guide appears to leave out the S prefixes on its serial number list, deduced from an observation made here:
These are most likely mid to late 1960s instruments.
3) Most (if not all) Buescher trumpets that have the "ELK" logo have a separate serial number listing.
They also bear the inscription "BUILT BY BUESCHER".
