    Weird Heliar 42 cm

    Hello, a friend of mine gave me this Heliar 42cm. The barrel is un lousy condition but iris and glass are quite OK so I would like to put it back to work. I found strange that the way the flange is positioned, the branded part goes inside camera body. But it leaves the aperture ring and a lens hood properly on the outside. Not sure if this lens hood is original because I have an Heliar 24 cm and it hasn't any. I would love to see a picture of a well maintained Heliar 42cm in barrel for comparison. Could anybody post one here? or any comments on this assembly?

    This is very different from the usual Heliar.

    Engraved as F4 (Normal is 4.5 or 3.5!).
    Iris between front and middle lens(Normal middle and rear lens!).
    Early heliars do have lens hoods.

    It has the usual brittle aluminium alloy in this sunken mount version - which explains why the iris has been moved.
    Obviously a special version made to suit special product. Military? Or is it possible it is somehow assembled incorrectly - I didn't think it was possible!

    Serial number would be useful?

    You've got all the necessary pieces. All it needs is to be re-assembled in the proper order. But it's obviously VERY fragile. I wish you the best of luck. Think about getting some of the copper "tape" that the stained glass window crowd use and wrapping that broken piece with several layers before you unscrew things. This stuff.

    Assembled incorrectly as far as I can tell and yes, that is possible on some lenses where the Iris cell unscrews from the barrel.

    As Jim said, needs to done carefully. The early aluminum is extremely brittle but yes, what a nice gift !

    Cheers,

    The one you have is special as the engraving is on the side of the barrel and says clearly F4!
    I have tried with an early 36cm to get the same misassembly as yours. It can't be done, it requires the iris being attached to the barrel and flange with threads. Perhaps this was standard practice with the 42, 48 and 60cm versions in the first few years of production?

    It is a 4,5...

    the "," is still visible but the "5" has mostly disappeared. In german decimals are separated with a ","

    Well spotted, Pere! (in fact the 5 is still hardly visible). Kudos to your eyes!

    I've seen too many heliars (that I can't buy) at ebay Also I think I don't deserve owning one...
