    HI, Milco,

    Recently, I scored a very nice 1945 #520, and when it arrived I was quite pleased with it. However, I soon found that the ball check in the NRV was stuck in the down position and would not hold pressure in the tank. Following Flivver's advice, I've now had the tank filled with lacquer thinner for about 10 hours. I'll give it until tomorrow, then empty the tank, rinse it out, and hit the ball check with compressed air, to see if it has come loose, which I expect it will have done.

    Very nice stoves, the 520's, and after seeing Flivver's, and Mac's at the CA Stove Gathering, I knew I had to have one, too!! Thanks for your great post on your own 520 adventure. Keep up the good work, and God Bless!

    Every Good Wish,
    Doc

    Hi Simbat

    I have a 1942 520 and it has the same cap as in the earlier photos of your 520.
    My 520 stoves from 1943 and 1944 have the filler cap with the screw in.

    Hi Trevor, I have tried the other cap also, but with the same result. It didn't fit also. See picture 5 in this thread. Can you tell me what the diameter of your cap is.

    Hi Doc, did you succeed in undoing the ball after 10 hours in thinner.

    Hello,

    The ball in the check valve is made out of chrome plated steel and therefore can be affected by a magnetic.
    One of those magnetic pickup tool can be used while the check valve is still in the tank.
    I find it is just easier to just remove the check valve. It only costs 2.50 (USD) for a new one.

    Smaller hole? Try a early speedmaster (500) cap or early 242 single mantel lantern cap. Mike...

    Hello,

    I found an other difference on the tank.
    The height is different, the left one is lower than then the right one. see picture. Did someone see this before??
    I don't get it anymore. :-k

    left is an American from 1941 the right one is a Coleman from 1942.
