Bearing in mind I"m looking at the image on the phone, but do they have a handle attached? If so and right way up possibly candle.snuffers, or inverted some sort of dip cup?
Gerry Anderson's attempt at making rocket stoves. Despite them not working at all well, the shape inspired him to create Thunderbird 3 - the rest is history.
Hi I have no idea what they are, but was told they had been on there a long time tho. 2 have the same markings and 1 another, but all 3 are basically the same whatever they use to be. Best bit was that all but 1 outer cap were present when I got to lift them off
@Tony Yes they are brass with a rim of solder and a ltitle brass tab on eac one, each also has a pressed small bulge not quite directly opposite the small tab, 2 at 11 oclock and the other a 1 o'clock. I haven't bothered searching the names as of yet. Cheers Barrett
