Good afternoon all! After a lot of fettling, fiddling and frowning, the good news is: I finally got a sustained Bunsen flame going on my Tilley Guardsman! A most satisfying moment! (the photos a bit rubbish but you get the idea!) The bad news, I could only achieve this by lighting it with the pricker rod removed as there is no spring in the vapouriser and the end of the pricker was getting stuck in the end of the vapouriser. Any suggestions on getting hold of a new spring?
