Here is a Doug Elliott Bass Trombone mouthpiece in mint condition. It has an "L" cup, a "L8K" shank but the rim has no designation. A photo of the rim might help those better informed than myself decide as to its proper designation. There is a tiny scratch on the rim that should pose no playing problems, the shank has no insertion marks and all three components come apart freely. The nomenclature of the various parts don't seem to match up evenly with Doug's latest listings, so I assume this is an earlier production model. There is a vertical line above the "L" on the shank that looks like a tool mark of some sort which can be clearly seen in the photos which I can provide in a PM upon receiving your EMail address. Asking $185/Offers including shipping in the CONUS.
