I've recently purchased this Vapalux 300. It wasn't quite running 100%. After a lot of head scratching and advice from @Gary Waller I've managed to get it running perfectly now. Im really pleased with this lamp. I intend to keep it in this condition as a 'working lamp' and to also retain the orginal decal.
These are great running lanterns. This one has a steel tank and appears to have no pressure tit so possibly 1943? There appears to be a date but I can't make it out.
I changed the usual seals and the lamp would run for a little bit then die. I eventually traced it back to a leaking air release seal (that I'd already replaced once) I changed it again and put a tiny smear of grease on the surface of the filler cap. Next up was the pump action, that seemed very stiff and on further inspection, I found this I got rid of the washer and nut, and replaced it with the correct nut with the slot in the back And it now pumps lovely. After a good clean around everything and cleaned the glass, here is the money shot
@Gareth Shepherd it looks great, at last working well. Probably one of my favourite lamps and really reliable.
I’ve got a slightly earlier version of the lamp and have been deliberating whether to restore it or not. It’s a bit further gone than yours finish wise, but seeing your lamp running and original is helping make my mind up, I think I’ll keep it as is for now. Just give it a good service and use it! Thanks for the inspiration Gareth!
