On a lark, I recently purchased a contrabass trombone. I need a mouthpiece for it. I've always heard and read that one uses a tuba mouthpiece with these, but this one's receiver is too small. Do you have something that might work?

Josef Klier contrabass trombone mouthpieces from Dillon Music. 3 sizes up to 31mm with 3 different cup depths. Works great in F/Eb contras.

I'm fairly sure the Bach 30CB would work also, it's intended for that application.

Michael, what horn did you get?

The Joseph Klier Kontra mouthpieces work well, and can be ordered with a normal bass trombone sized shank or one slightly larger for some Europeon contras that take a larger mpc. Slide contra trombones are often played by a bass trombone player, and even the largest bass bone mpcs are a bit small in the rim for contra, so the JK contra mpcs in between bass trombone and tuba in rim size. I have a 2A and a 2C, like the 2A better on slide contra and the 2C better on Cimbasso. (with a JK tuba shank adapter) However it seems you want a tuba sized rim. The JK tuba mouthpieces are available with cup depths suitable for contra trombone and cimbasso, and can be ordered with a bass trombone shank, they call it the 12.5mm shank. I have a JK 6D tuba mouthpiece with a bass trombone shank, tuba sized rim, shallow cup, works well on Contra in F, BBb, and Cimbasso. You will probably have to special order, I have gone through Dillons and it takes a few weeks although Dillons has good prices. HTH

Nothing fancy. It's a Jinbao. (First time I've seen an actual Jinbao-branded instrument.)

I've been curious about contrabass trombones for a while, and one popped up for a price that made it worth experimenting with. I don't know that I'll keep it long, but who knows.
