This is a beautiful Buescher Aristocrat 255 made in 1955. It's in raw brass. The 244 model appeared in the 1950s with hexagonal valve caps (tops and bottoms) and with the 3rd slide on the left side of the trumpet (from the players perspective). Prior to this almost all trumpets Buescher produced had the 3rd slide in a "reverse wrap" format (to the right of the main slide). This model also features the trombone style water keys.
This is a fantastic playing example of the 244 model.
