I could use the RPFs hunting ability! I found this bracket on a certain auction site and bought it. if anything, I get a couple cool knobs, but look at the bottom left. That could be our "aluminum track" fake graflex clamp. No freaking clue what camera it belongs to.

Oh that's the one with the thick black band at the top of the grips. Only a poor image existed until now. No clamp ( @Marv; was right). Fake control box.
