    Hi,
    I'm looking for an ID on this control cock please.
    It's all brass with a ball bearing inside as a shutoff, along with the the lower spring valve. There is broken vapouriser end included which keeps the ball in place.
    TIA,

    This XN control valve was the one that followed the first hexagonal control cock
    I think it was in use on lamps from 1924 till 1928ish. After that they looked the same but had a back screw(opposite the knob)to support the far end of the control shaft.
    Various brass valves followed this one its a nice thing to have.
    Cheers pete

    And?
    Just getting it to the right person, it was always getting sold, better with someone who actually wants it than in the bottom of a box. You make out like there's some law against selling stuff. If that's the case you and no one else would have a collection, unless of course all of yours came out of skips. Thanks for the ID and it was available to buy within about 24hrs, not within a week! Have a look at the fairly inactive trading post page here, what do you expect?
