This stove's filler cap is tapered and pushes on a pin in the filler neck to control fuel flow. The pin is connected via a spring-loaded linkage that rides out of view above the fuel tank to the valve at the burner. Fuel (alcohol) cannot flow to the burner when the filler cap is removed.
Hi Gary, you have an interesting alcohol stove there. I have a drawing of the Stove in the 1957 Primus Catalogue, but it has no fiddle rails, nor holes in the frame-work to fit them. I believe that your stove was probably intended for use on a boat, and that is why the fiddle rails are fitted. Lovely stove. Best Regards, Kerophile.
Hi Gary, it is interesting what you say about the flame control being via the filler cap. In the 1948 Primus catalogue: https://classiccampstoves.com/threads/193 It says that there is a safety feature with this stove; if the filler cap is removed in order to re-fill the tank, the flame is automatically extinguished. Best Regards, Kerophile.
I like those little alky stoves and have been dragging one to Rondy's lately. I really appreciate the quiet and the lack of toxicity of the fuel. Although it's not the cheapest fuel, the almost universal availability has much to recommend it. Oh, yeah. Welcome to the CCS forums. I forgot my manners there. Gerry
