Hiya, This veritable beauty wasn't "far gone" when I recently won it over in Ebay.com. I had a lot of work to do though, it turned out; this wasn't something I'd anticipated, just by looking at its main overall appearance from the out set. After the main fettle & polish up, the fuel/ air assy was behaving like a mad dragon, suffering no continual fuel flow, with anything deemed fit for use. As I'd fettled it first (bit of an error there), I was lucky to get some good advice from NE, USA (Cheers Dd) ., and suggested that if I didn't want to risk "digging out" the main valve & F/A assy (potentially ruining the tank in the process/ stuck fast in real bad, it was), the safest way first, would be to try to "clear & irrigate out", all the lower detritus & oxidization, most probably causing the foul up ! Using some potent "rust remover", I seeped plenty in, down the main valves (bare) "thimble cup res", spending many hours before, beginning prior, totally masking off the founts fruity & pristine paint work. The safety masking/ de-masking, in between all the different cleaning/ application processes, is what stretched out the main brunt of the work; but it was essential if I was to do no damage, to what had miraculously lasted 50 yrs, without much 'a do' ! Pressurized air canisters, helped "blast out" what ever there was left in there, "sticking" the torsion coil spring, to the F/A's clearing rod needle. After all that, I gave it a good "flip soaking" in Marine Clean degreaser solution, as well as adding to this some small nuts, screws & pebbles, to shake out & knock off any obstinate portions, still reluctant to break free. When it seemed as clear as I could get it, I then fully dried the fount unit out, then proceeded to "work" the main, off/ on valve wheel (repetitively), with the fount half full with kero. I've purposely missed out a lot of the "other stuff" I also had to do (too long a type, ect), but basically after the "kero" had lubricated the F/A's workings, freeing it up much more than before, I did the same thing with "Naptha/ White Gas", only I fitted the generator back on this time (minus the stuffing), just to "see & hear" how/ if, the system was faring any better ? I'd not spent as many days (if not weeks), meddling around with a 'problem lantern' like this before, but all the effort, on that "second fire up" attempt, proved to have just done the trick; the lantern didn't "conform", on the "quarter turn", at first, but taking it near to a "full turn", time & time again, I found on each subsequent "light up", it successfully pre-heated, nearer back towards its preferable quart turn dynamic ? It could possibly have just been acclimatizing & re-setting itself; if not that, possibly it still could have been burgeoning itself of more grunge, clearing free from the F/A assy ?! Mighty fine though now, lights every time without fail, & the brightness from the Sears mantles I attached, was just phenomenal ! This one's a very quite burner, which has me suspecting "something's" still not quite right ? 'It hasn't spluttered, threatened back up or fluttering' at all, the clearing assy works sweet enough, "no tightness, requiring resistance on swivel turn"; I'd suspected it could have been a "reject", as there was quite a few parts, during the fettle up, that were marked with flaws & irregularities, I'd not seen or noticed that much before, with all the other US lanterns I'd worked on (this may be more usual though, the many score thousands, manufactured) ? Well, for one thing, that could explain why it appeared almost "brand new" on receiver ship; it mightn't have been lit more than half a dozen times, if that; the burner & generator were very clean, up top, & the only real damage, aesthetically, was to the underside of the collar, where the paint had been slightly marred & coursed, whilst being sat all those years. "Enough of the rabbiting then, here's the new look lantern", I like it a lot, finally ! "phewww, hard work, that one. . . . . . . " ! I hope this 6th one loads ?! Cheers, Jon .
