    First post here so go easy please.
    Just purchased this from the bay. New to all this so here goes!
    Tank is in good condition just dirty and clean inside.
    There’s two types of control cock apparently, not sure which one this is.
    The springs are on the inside of the gallery bit, 1940’s? The pricker works fine.
    There’s no mantle yet but there seems to be the remnants of something in the upper mantle groove?
    The globe is aftermarket with no markings and there isn’t any kind of pressure release on the tank anywhere.
    The pump seems to work ok.
    I’m waiting for a service kit to replace seals etc and I’ll oil the pump leather.
    Can’t see anything wrong as yet but I haven’t stripped the pump yet!
    I bow to you more knowledgeable folk.
    Any info is extremely appreciated.

    Welcome, @Dave Gidman.

    The ring in the mantle groove is the remnants of a Tilley “Happy” mantle and should be removed.

    Cheers

    Tony

    Ha! Crossed with the Pod.

    @Dave Gidman

    A few things to come back on:

    1. The control cock is a GF cock (1940 onwards). Check the riser tube/handle and see how deep the area is that the cock screws into. Would it take the much longer XN cock?

    2. Does the bottom rim of the tank have any stampings on it?


    Cheers

    Tony

    It looks like there was something stamped there but I can’t tell what it used to say.

    Dave

    That is the Registered design stamp.

    The next thing to check is that the tank is brass, not steel (a war time economy).

    Cheers

    @Tony Press Definitely brass, I gave it a quick polish earlier.
    I can’t see anything else stamped around there. I’ve just been on the Terry-Marsh site and I think this is mine on the left. Perhaps it is a TL10 without the shade?
    I read the Neil McRae piece about the different TL’s so I don’t suppose it matters what it is really. Lovely thing whatever’s on top.

    Thank you Everybody for the replies. I’m getting my head around this lamp now. (It only got delivered this morning) GF Control cock, brass, 1940’s TL10 with an aftermarket glass globe instead of its original glass shade by the looks of things. Sound about right?

    IMG_6376.jpeg AND THERE IT IS!
    Heard about them but this is my first. Right above that stamp. I couldn’t see it with my naked eye but in one of the photo’s yesterday it stood out like a sore thumb (Thanks pb). In my defence the tank is filthy.
    Is grinding a v in the crack and filling with solder a viable fix or have I bought a door stop?
    I’m going to try a pressure test today with the original seals.

    Definitely give it a good pump up

    it may still be ok as there is a lot of solder on the inside as that is where the base plate sits so fingers crossed for that :thumbup:

    yes, the carefully grooved channel via dremel with some solder is very viable too

    good luck with the test Dave :thumbup::thumbup:

    Edit ** there is a fettlers masterclass on the stress crack repair theme in the Fettling Forum :thumbup:

    its a great read

    Thanks pb. I’m all for a bit of a fettle! Nothing ventured and all that. Got my Dremel at the ready.

    IMG_6377.jpeg Apologies for the crappy photo’s. Done the leak test. No leaks. Gave the tank a quick whip over with the Dremel and found another equidistant the other side of the pump in exactly the same place on that rim.
    it’s getting a few hours with a cloth and Autosol tonight then I think I’ll try the solder thing.
