Hello, picked this up a couple of weeks ago from fleabay in the UK. It has a 1051 burner / vapourising tube that all seems to be a piece. The only replaceable part of it seems to be the nipple. I managed to get it going after a bit of cleaning and spraying the rust-prone parts in clear-coat lacquer. The original chrome is long gone. I like how it runs. I'm using Holt's Brake Cleaner and it seems to run cleaner (pun intended) and more freely than paraffin. Also using mantles from Base-Camp, no. 6176. They seem just the right size. The main issue, among many was that I could not get the NRV out to replace rubber nipple. Unfortunately the valve edges have rounded off and don't fancy unsoldering the pump to get it out. Any alternative suggestions welcome. A small amount of liquid leaks into the pump chamber. Luckily the pump handle can screw into the top of the pump chamber.
