Hi all. I found this superb forum after digging out a Tilley 246 ( as I now know it) that had hung up in my barn for about 25 years. I decided to give it a clean and get it going. First item on the list was a new pump piston, as the end fell off the old one. Then a new seal kit, when I became covered in paraffin after pumping it up. The NRV was refitted the right way round, and a new spring added. The kit came with a little rubber disc that I stuck to the end of the plastic NRV pip thing, but then the whole thing bottomed out and wouldn't open when the guide was screwed in. I trimmed the disc a bit and shortened the spring, and all was good. A bit of pumping and preheating, and away she went. I was amazed at the amount of light and heat. It's my new favourite toy. Her indoors was less enthusiastic then I was when I marched into the kitchen proclaiming the awesomeness of my lamp, but was quite impressed when it raised the room temperature from 21 degrees to 25 in about half an hour. (it's not a small kitchen, either). It will give some welcome extra warmth in my freezing workshop, and provide many happy hours of browsing for new lamps on Ebay. Anyway, I did have a question. Do the brass NRV things I see advertised fit my pump, which is an ugly new aluminium-ended job? thanks in anticipation, and sorry for the rambling, but I'm VERY pleased with my lamp. So much better than the Coleman propane North Star I use for fishing and camping.
