Well, there it says "get all BB meshes here" - and on the MTS2 site are just the "normal" meshes.
And the linked recolors from Engelchen include recolors for each and every BB mesh, not just the planter2large or whatever it was.
Well, I guess I was wrong then and there was no slaved set here on the forum somewhere. What a shame, I think that would be a pretty good idea :-)
