This is an Edwards B2 silver pipe that has been modified to be playable with a Shires setup. Shires threads have been installed. It has been cut slightly shorter to my preference, about 1cm. For reference, I've attached an image comparing its length to a standard Shires brass pipe. (The brass pipe is not included.) Even after cutting, it is still longer than a standard brass pipe. The threads from a Shires 1st valve slide have been used, and a technician has stamped "B 1 + 1" to indicate that it is for the 2nd valve slide.
