    Hi! This lamp is incomplete but i managed to make it working.
    I need to find a right cleaning needle, the one it have is worn and to short. I didn't found any number on it, but the vaporizer is the same as the one on this lamp 1934 Ditmar Maxim N° 503
    I can pierce the jet with a 200cp needle (from radius 143), the 300cp (from radius 119 is to thick) so i believe it's a 200cp lamp.
    The jet is similar to the one from coleman 200 early type.
    I'm missing the hat (i believe that is 2 parts hat), probably a priming cup (or a heat deflector) and a ring between the glass cage and the tank (I'm going to try to put a Radius 119 ring).
    Some cleaning needles someone?
    Cheers,
    Francisc

    In the Ditmar 503 there is no priming cup. Preheating is made either with a "fuel torch", which is a piece of folded sheet metal, containing an asbestos wick. This torch is first soaked in petrol in the tank, lit, and then inserted from below through the slot in the bottom of the globe cage. The sheet metal brazed onto the vaporizer conducts the heat of the torch's flame to the vaporizer. So a small butane torch or a big match can also be used to preheat.

    Usually there should be a heat deflector over the central screw of the globe cage, which seems to be broken off or replaced at your lantern.

    Needles are impossible to get. You can try to make your own from e. g. a cannibalized Coleman vaporizer.

    Glass cylinders from 300/500 CP Petromax type lanterns and their clones will fit from the diameter, but are a few millimeters too short. Original cylinders are also very rare. You could try to get a mica cylinder made for this lantern. Also all other parts for these types of lanterns are hard to come by, and the best would be to akquire some spare parts donors.

    @Martin K. Thanks for all the information.
    I have the original glass with the hole in middle but unfortunately it has a crack on half of the glass.
    But maybe i should try making a hole like i did in this glass ( i comes handy niw to use with a ditmar 519). Not the nices hole, but the glass survived
    Cheers,

    Hi Michel! No i didn't tried with a match. I used a bit fiberglass rope with a wire inside soaked with spirit.
    I hope i see yours in action soon!
    Cheers,
