Thread: C.P. Goerz Berlin Serial numbers? (Dogmar)

    C.P. Goerz Berlin Serial numbers? (Dogmar)

    Does anyone have a list of C.P. Goerz Berlin serial numbers? I have searched the net, but only found the numbers from the american branch.

    I got a Dogmar 6,3/135mm (S/N 353458) today, and according to the Vademecum it was only produced for a short time.

    I wonder why the Dogmar isn't a "cult lens"? It was, and still is, Goerz improved version of the Syntor/Celor.

    Patric, if you go to the bottom of the Goerz section of the Vademecum there is a chronology which should place your lens at about introduction in 1915/16.

    1915/16 could be correct. The Tenax camera I got the lens from looks like it could be from the 1910's.

    There's no chronology in my Vade Mecum. I have the second edition.

    I took some test shots yesterday, with the Dogmar on a 6,5 x 9 Voigtländer Bergheil. Exciting.

    Patric, in the third edition of Les Chiffres Clés P-H Pont gives this chronology:

    up to 5,000 -- up to 1891
    30,000 -- 1896
    100,000 -- 1900
    200,000 -- 1908
    300,000 -- 1915
    400,000 -- 1920
    500,000 -- 1922
    600,000 -- 1923
    750,000 -- 1926

    After the merger with CZJ, Goerz lenses' serial numbers were in the CZJ sequence.

    Hi there,

    I just picked up another 420 Dogmar, #661178, it's also stamped with the factory Zeiss/Ikon logo and #43633, so I guess this is after the merger. Now to replace the missing aperture assembly.

    Thanks, Dan. I'm saving the list.

    I know this thread is a little old but I just picked up a 420 dogmar myself and mine is also missing the aperture mechanism, small world, anyway I was wondering if you ever found replacement parts or created something that would work, thanks.

    I have a 420 also, and it has had rave reviews from any print I have presented.

    Actually I have 3, the other 2 work well. The easiest 'fix' would be to remove the outer ring and fit waterhouse stops or washer stops. You could goggle 'iris aperture' and see if anyone has them in the right size but that's expensive and time comsuming to fit and scale. I did that for the 480, handy but I think you should try the washer stops first to see which f/stop you usually use OR if you use all of them.

    "I have a 420 also, and it has had rave reviews from any print I have presented."

    Acura is the 'better BMW', Dogmar is the 'better Heliar'.

    Sorry but I do have quite a few of each.

    I did check and Edmond Optical does have an iris assm. to fit (92mm OD)
    $200 + fitting + setting the aperture scale + time out.
