Had same year vintage BA Tenor which I sold 3 years ago for a ref 36. My BA tenor had nice sound qualities for sure but bottom end intonation as mentioned by Tharrfuff and overall playablity sound and ergos compared to ref 36 was no comparison
But to each his own.
BTW I still play a BA alto 1938 vintage which I would never sell, but was never really atisfied with the BA tenor.

erhaps the one you are looking at is better.
