I am currently in the process of designing a folding field camera similar to the Ebony SV810. What I can't seem to figure out is how the focusing knobs are laid out. Is there a single knob for each standard? Is there a shaft that runs to both sides of the standard?

If it isn't too much to ask, could someone post a few close up, detail shots of the focus bed of an SV810? I'm curious to see how it's all laid out.

Thanks!

(Also if anyone has them, exact dimensions for a deardorf 6x6 RC lens board and receiver would be dandy.)
