These may just be THE most undervalued horns on the vintage market. It has the same body, neck with underslung octave mechanism and keywork as the famous older brother the 'Top Hat' model, but with nickel plated keys and rear-bell keys. It's safe to say: Last of the real Bueschers.
This is sax is 100% classic Buescher even if the buyout happened.
Due to the serial number being covered by an added thumbhook soldered on, you can't see digit-three in the ser#, so that's my lean to the 1962 option, otherwise #381k start 1963 and the Selmer buy-out era. There were only about 40,000 of this model made, and this is near the end of that run. It's the ultimate 'Budget TH&C', 'Sleeper', 'Player's Horn', and head-turner!
Little brother to the Top Hat & Cane model, this is the near-identical sax with a different engraving and minor changes. (on Consignment - Plays OK to low D ( minor adjustments to discuss))
