This is a late vintage original silver Buescher True Tone. These late models are highly sought after by players for the high F in the palm keys and stable intonation. The original owner did a fantastic job caring for this instrument and it also features the original wood Conn case.
The original silver finish looks incredible. There is also no history of major body work on the sax. It was overhauled in the Saxquest shop in 2013 by Chris Watrous.
