I'm beginning to feel like an archaeologist. Found one last piece and I've never seen anything like this before. It's some sort of telephoto lens and it's focused via a trigger like handle. The reference to Bronica is merely a UV filter. The lens functions, clean glass though the diaphragm is a bit stiff, it too works. Anyone ever seen anything like this?
Sweet, a Hasselblad Photo-Sniper. (Zenit, I think - some Russian company - has a similar system for telephoto lenses on a 35mm SLR).
