M & B 2GBT I full gold plate & satin finish. This is a fantastic 2G sized mouthpiece, it's very easy to play & has one of, if not the most comfortable rims I've played on but I just need to be on a slightly bigger size. The overall condition is really good with the usual shank wear (why do they gold plate the shank?!) & some small scuffs to the satin finish but these are purely cosmetic.
