Vincent Bach Corp 8 Early Elkhart model, no dots. It's a small shank mouthpiece with an inner diameter of 24.75mm, a medium depth cup, and a slightly wide, flat rim. There is some plating wear on the shank, but it doesn't affect playability, and it's in good condition for its age. I've been collecting it, but I'm putting it up for sale. Please take this opportunity to purchase it.
