A Primus 41 sp, brass, silent burner marked AR (1952) in fair used condition. Came with Primus No. 1738 spirit bottle, Primus jet removal tool and pilot light. Burner is regulated No. 4155 , with carrier/needle ( history here ) unhinged spindle. No instructions, box or burner pre-heater. To get her safely operational from as-is condition, she just needed a new pip (replaced cork original) and spring in her NRV and a new fuel cap gasket (cut from 1/16th" viton). Her leather pump cup was fine, just needed some oiling (3:1). Original needle on carrier was broken and was replaced with new one. No dings on the case, just some surface rust on front and inside bottom. Fuel tank has an impact dent on her left side. Primus label on top. I like the original dusky matt-green paint on these. I made a pre-heater/windshield for her from a Friskies tin (cat food) and cut/size/grinded to shape. Tank and burner were in pretty rough shape dirt wise but they cleaned and polished ok. Pilot light and Primus jet removal/key tool. The nipple removal key has a few other slots for various bolts and has 'PRIMUS SWEDEN' on one side of her Ubiquitous spirit tin, No. 1738, front label Back label Inside brass fuel cap is a cork gasket. Nice knurled edging. Original outer silent cap labelled 'PRIMUS METAL No 4209 SWEDEN' and has 5 rows of hole No labelling on SVR-less fuel or pump cap. On brass tank is found 'No 41 TRADEMARK PRIMUS A/B B.A.HJORTH & Co. SWEDEN' Date stamping of AR for 1952. Brass spirit dish with the words 'PRIMUS SWEDEN' on the inside bottom of it and the outer ring of the burner has 'PRIMUS SWEDEN' in addition to some Islamic words stamped into her. Unhinged spindle with partial remains of her chain. Was also missing her 'locking' sheath to screw into burner at fuel control valve. Her spindle has since been replaced with equivalent that has sheath (not shown). Drop-down pot support in good shape, just a little dirty and some surface rust. Stove lit and running on medium-high. Medium setting. These are fairly well designed stoves and are excellent performers. They use kerosene as fuel and have a large (1 pint) tank capacity. Their burners have an excellent heat range and flame consistency: can sustain high heat outputs for deep frying or the lowest of simmers for rice. Their steel cases are very durable but their handle-latch mechanism is a little awkward. The inside top lid has a fold-out, hinged flat steel windshield that hooks into the pot support frame when deployed. They date back to 1940 and were in production until the late 1950's. They do have a number of limitations/drawbacks including: an exposed tank when in use (runs outside of case - more prone to damage/dents): when the windshield is deployed it limits the size of pots you can set upon her pot support: they are heavy: they must be used on flat surface; carrier/needle combination can be problematic; somewhat flawed burner design regarding the carrier; burner very close to tank (anything larger than small pot will sit above the fuel tank; no SRV; questionable closing mechanism.
