    It came with the glass handle as so many of these do despite the lack of a shade.
    I can only assume that it once had one in order to make it a 930A.

    I don't miss the shade one bit. It's one of the ugliest accessories we can find for any lantern.
    But the handle is still very handy even when using it as a regular lantern.
    Since these run so hot, it's easier to pump or move them with that convenient little grip on the side (seen on the third thumbnail).

    One funny detail is that it had a 500CP jet mounted, as you can see here:

    I deceided to try it out with that one since the old mantle it had when I got it was nice and all white.
    There was actually a little chance that the former owner had it working with this large jet, and since the 930's aren't too picky about jet size, I gave it a go.
    It worked, but it wasn't bright white, and it had a bit of a glow outside the large mantle I tied to it.
    So it will have to be a swap to a more proper jet later on. Probably a 300CP.


    I had to remove the pick-up tube since they had used a rubber washer to seal it up instead of the proper lead.
    Well, the lead was still there, so I just had to add a thinner lead washer in order to be able to align the control wheel correctly.
    I use a very thin lead to make thin washers to sort of shim things that has been loosened.
    As you know, it's not possible to get a lead washer sealed thing come to the former postion and still be sealing once loosened.
    A strip of lead that's only as thick as a revolution of one turn of the threads of the object in question is generally suitable.
    The thicker lead washer is just there for illustration of the 'normal' (homemade) one:

    Testing for leaks. No bubbles; no troubles!
    Oh, well... of course there are bubbles. But only where they are supposed to be - from the jet:
