Reeves Trumpet Mouthpiece Underpart Only

The bottom portion of a Bob Reeves Brass mouthpiece if you already have a Reeves rim. Choose the rim diameter, cup shape, backbore size, and shank style. We ask for the rim diameter to get a proper match even though a rim is not included. Please note - the photo shows both rim and underpart, however, only this item is for only the underpart.
