Anyone know what grade of gauze is used in the strainer in the 96 vapouriser. I've just got hold of a 1931 Primus 96 but the strainer is missing. Looking on ebay I'm guessing 60 (37SWG) or 80 (39SWG). Thanks in advance.
It's a quite fine but not extremely fine brass gauze - the main thing is to enlarge the vapourization area, not filtering the fuel - it should have a firm fit in the "lipstick" to work properly.
