    I've had this for a few weeks but only today did I get round to finally finishing it.

    The fount was suffering from quite a few rust spots and once treated they left some pitting behind, but the collar, frame and hood all cleaned up nicely. The label has come off but I can reattach it easily enough.

    I hadn't planned to convert it to kero but the first time I tried a test lighting I discovered that there was a blockage in the generator and the pricker needle had broken so I swapped it out for a 339 genny and a pre-heater cup and she roared into life. Thanks to finn-emm (that's his eBay handle because I've forgotten his CPL name!) for the lamp and replacement control valve and @Norman for the pre-heater and loads of other help.

    :lol: @ColinG , I did almost the opposite: I traded for a green 335 that had been converted to kero and converted it back to CF. Although they are not particularly well regarded by the Americans, I've always rather liked the 335 and 339. Very quick to pre-heat, very bright, a nice compact size and a cheap/common standard globe make them great camping and travelling lanterns.

    It's very bright and starts after half a cup of meths - almost as good as my Veritas Superb!

    Running well.
    Out of interest, when lit, is it more of a gentle roar than a hiss? I'm working on a 339 and although bright, it is noisy in comparison to Tilley

    Not really a roar... maybe a bit louder than a Tilley but most Colemans are a bit noisier... then again most are a lot brighter too!

    So, what did you do about the 335 fuel-air tube in the fount , Colin?
    Also, did you know that the top end of burner tube on the 335 is restricted but on the 339 it is just a straight tube?

    I did nothing apart from change the generator and it seems to work perfectly. It burns evenly, it's very bright and although it's noisier than a Tilley it's about the same as most other Colemans I've used.

    Nice conversion well done.. a gem , myself I converted a Coleman 295 dual fuel to run on kerosene by swapping the generator tube for a 639 tube .. an exact fit and adding a copper pre heat cup .. worked great .. but the glass suffered and was cracked with the heat. Now a Coleman 639 lantern has a bulbous glass piece a little further away we see from the mantle.. it was probably designed that way but hey ho just keep watch on the glass good luck:thumbup:

    That's a great idea, Alby. I have a bulbous globe and a 639 generator as well I think, so this may well happen soon.
