Description Rotary Valve Trumpet in Bb This Rotary Valve Trumpet in Bb is by an unknown maker, there is a logo on the bell (as pictured) but it is not one that we recognise. It has a small bore that blows well with a warm tone. All slides move and the rotary valves are working. The raw brass finish has a nice patina to it. Comes supplied in a woodshell case and with a mouthpiece. Second Hand Instruments  Our second hand instruments are serviced before being offered for sale, and are subject to six months guarantee.
