WTB: Copper Tuning Slide for Bach 42B

[ttf_anonymous]

I realize this is a stretch, as someone who would go through the effort of getting one of these isn't likely to want to offload it, but I thought i would give it a try.

Previously, I asked for Hoelle brand specifically, but now i realize there are a number of custom tuning slide makers. Any of them will do, i think.

Self-explanatory - looking for copper, ideally - but might consider rose brass.

Thanks!
