Leica Tribrachs/for parts

Hi,

I'm looking for old, broken, for parts - Leica Tribrachs.

I cannot find parts for these to be able to fix what I currently have. So I'd like to buy at least one broken/for parts to be able to fix up my current equipment.

I know, just buy a new one, but where's the fun in that?

Anyway, that's the gist. Thanks
