This is a 1949 Buescher “Big B” Aristocrat, so named for the ornate engraving of a, well, a Big B on the bell. This horn is in very good condition, and the typical wear around the fine engraving of the B on the bell is not present, which indicates that this horn has led a life mostly in a closet somewhere. There are no resolders or past dentwork to speak of, and it plays *way* better than it should on some very old pads, but you would want to get this repadded to play like it can, which is very, very well!
These horns are undervalued in my opinion. I mean, you can get this one in such great shape with all of its original Snap-on resonators and overhaul it for not a whole lot more than a Yamaha student model in total- seems like a good buy to me! They combine excellent intonation, comfortable keywork, top notch build quality, and beautiful lacquer and engraving with a warm, centered tone. Johnny Hodges famously played one of these, and his tone is a very good example of the blend of sweetness and power these horns possess.
