    Hi,

    I've an old battered MPP Mark III which I am trying to repair.

    The range-finder seems to work well, but is not linked to the bed. There is an arm, ending in a small chrome bearing. There is a bracket coming out the the right hand side of the front standard (viewed from the ground glass) which is chromed, parallel to (and just above) the bed and has a 'V' shape cut into it, facing rearwards.

    Whatever goes between this bracket and the bearing is missing.

    On the MPP users site there is a lot of information about cams for the later models of cameras with instructions on how to make different shapes for different lenses - but nothing for the Mark III.

    It actually states in one article:
    "MicroTechnical Cameras Mk's IIR and III do not have Rangefinder Cam Plates."

    Does anyone have any idea what should go between the arm and the bracket?

    Thanks.

    I have a couple of the MPP cameras, one with an intact/complete range finder fitted, the other stripped out. Give me a day or so to find an extension tube for the digisnapper, and I can photograph(sic) the gubbins for you.

    The cam plates are attached to a small bracket on the right hand side of the bed about 1.25" from the hinge right next to the V groove - The groove is only there to act as a guide for the RF arm as the case is being closed up. On re-reading your post, I suspect that all you are missing is the cam plate (these are matched to individual lenses so are not interchangeable).

    Yes please, that would be great. There's quite a lot of information on the Net about the later cameras - but I couldn't find a single picture of a MK III that showed this linkage anywhere.
    Thanks!

    Hi,

    Thanks for the reply and taking the trouble to post the pictures.

    Unfortunately my camera has a different range-finder, I believe.

    The later cameras the range-finder arm seems to move up and down, viewed from the range-finder side it rotates anti-clockwise as the camera bed moved back into the body

    My range-finder, being on a MK III, is similar to (maybe the same) as a speed Graphic. The arm moves back and forth, it rotates clockwise as the camera moves back.

    I'll attempt to post a picture:

    Click on the thumbnail and you'll see the chrome arm of the rangefinder just hanging free. On the front standard is a chrome bracket with the 'V' cut out - but nothing contacts the arm as the bed moves back...

    I had a cursory look at the MPP users club site and it did occur to me (during the early hours) that I may have goofed. If the rangefinder on your camera is the Kalart design, perhaps these two might help:
