    That's a Horseman roll film holder, so not really strange. The screws on the long side appear to be holding it in place. Or are they for the slider? Perhaps removing them would let you change the holder?

    Hi Laurent,

    Yes I did.I do have 150 close, 210 close and 270 close cams, however they do need some "finishing". I have contacted my colleague who was filing down the cams so they fit and lock in the slot, but he is busy with other things currently. You do not need "normal" cams, as the the close cams will be the same until they are "close".

    I also have a solution to your need for a 4x5 back, if you scroll back through this posting. Again though the plates need finishing to work.

    The original film holder piece is a spring-loaded clamp that can allow basically any holder to fit, including grafmatics. Sadly, they are not easy to come by, you would likely have to fabricate something. If you search google or elsewhere for images of the TWR you can see the part and how it works. It slides into that groove and is retained with a pin (spring-loaded) and there is a surface for the filmholder to sit on. A large spring clamp holds the film holder snug to the surface. The 150 xenar was the standard 150 lens for these, I have one that came with mine, but I also use other 150s including apo sironar s and xenotar.

    hi Laurent -

    those are nice fabrications, whomever made those was doing some nice work. If you can find the original piece, that will be your best bet, since it allows all film holders to fit (incl. Grafmatics, Polaroid holders, etc.). I wish they had made this a graflok back instead of a spring back, originally. IT would have made things easier and even lighter. unfortunately converting it to a graflok back is a significant bit of machine work.

    Good luck, it's a great camera and worth the effort,

    -Ed

    Had the pleasure of once using a Cambo, Gowlandflex, and a home made version in a studio setting. Found the Cambo to be the best of the lot. You acquired one fine camera... enjoy.

Fortunately I knew someone who could get aluminium lasercut and I had the plate made that slides into the slot. This cut plate, aluminium block and second plate, a couple of bolts, some felt as a light-trap, neoprene foam as a tensioner and I have good grafmatic holder.

    Hi Laurent,

    This is what I was talking about.
