    Part Needed for Linhof Color main rail clamp knob...Red.

    Hello everyone,

    Just looking into the possibility that a member may have parts on hand for a Linhof Color 4x5 camera...in particular, the Red (Bakelite?) main rail clamp
    knob as seen in the photo below. Currently, using a metric wing-nut, works ok, looks like crap.

    Let me know if you have an extra you can part with and what you're looking $ for it.

    Best,
    Jason

    Good luck! Those are the dumbest thing Linhof ever did. They are really the only weak point. I have bought entire cameras just to get those stupid knobs.

    I love the cameras, but not the knobs.

    Aluminum knobs would have been a far better choice in retrospect. These were always expensive cameras and this 'cost savings' is not so German...

    I'm sorry, but I have none to spare and your solution is best!

    No idea, but not a fan of that approach. Just simply have this nice old camera I enjoy shooting with when the spirit catches me, and
    just wanted to get the right knob for it.

    You might look to knobs from Mcmaster Carr. I replaced the often broken plastic knobs with steel versions from them.

    All of the parts that Marflex had left, both new and salvaged, were bought by Nippon Photo Clinic so you might start by contacting them in NYC.

    Jac,
    I'm doing a little research out of interest. I think it's safe to assume these Linhof handles were made out of Bakelite? I agree with Randy Above, that
    it would have been better to go with a polished aluminum knob, but Bakelite was a pretty amazing product in its day...and it definitely made the
    appearance of the camera pop when compared to many others of its time. Going with Bakelite with brass inserts would have been much cheaper.

    I have considered copying the handle in cad and then machining replacements in aluminum, fortunately, I have the time to waste and the means,
    (not if you ask my wife though) but I for one like the old Bakelite. ;o)

    Although Bakelite was fragile, I'm never ceased to be amazed at all the old stuff made out of it which is still intact. Apparently as long as it wasn't bashed against something, it doesn't structurally deteriorate. I'm thinking of 23 Century Graphics -- bodies still perfect. Also, I think that all of those cast-iron Bell Telephones were bakelite? I have developing tanks from the 50s which still seem perfect.

    If you do make a CAD Copy, please consider sharing the file, I need a few. I would consider a shape redesign also, as the knobs really hurt my hands when very tight. They are very knobby!

    The picture below shows my 1950's Linhof Color Kardan 8x10. It has 9X9" lensboard and in this image it is holding a 8X8" Deardorff lens board with a Kodak 405mm Portrait lens and an internal Packard shutter. Very heavy contraption, but sturdy.

    This triple standard setup has 23 Bakelite knobs!!! and 1 OE Linhof aluminum knob on the tripod.. I'm not counting the 3 more black Bakelite tilt lock knobs which also break. It's my show piece with everything working and no broken knobs, I have a second 'parts' camera that is in dire need.

    On this very heavy camera, I think breakage happened when 2 men, it requires 2 men to take it off the dedicated tripod and they put it on the floor where it falls right over and breaks some knobs. The cursing is still in the air! The removal was driven by the tripod design, which has optional parts allowing many configurations after you take the monster off the stand.

    I also have the same camera as you in smaller 6x9 and I am very gentle with my baby, it lives in a padded cell...
