I have an early Linhof Technika that probably was sold with an European-style revolving 13x18cm back. The serial number is fuzzy, but looks like 17,334. Someone later evidently added a 5x7 Graflok-type back, but looking at the tool marks, I assume it was NOT done by Linhof. Modern plastic 5x7 holders fit are a good fit, with no light leaks.

And the back is frozen in the "landscape" mode... as it does not have a side-mounted tripod socket like a Crown Graphic, I'm certain it originally revolved. A Photo.net user has a very similar model to mine, and he says his has no lock for his revolving back, and just has four easy-to-move detents to hold the back in four possible positions.

So any ideas on how to make it revolve? What would be the first step for disassembly? If it is indeed GLUED forever in the "landscape" mode, I have a beat-up "parts" Anniversary Speed Graphic, and may try and mount its tripod socket on the side of my Linhof. Thanks for any comments or suggestions.
