A brass Primus 340 sp, coded AI for 1944. These made their appearance during WW2 and ran for at least a few years post-war. The burner is No 3025 designed to run alcohol due in part to the availability issues of kerosene and petrol (coleman fuel). Besides the instructions and original box she appears to be complete. As a 'bonus' this one came with a Svea No. 774 brass windshield (shown as deployed). She doesn't show any verdigris, just a few scratches and has a decent patina so I do not think at this point I'll be polishing her up. I'm a user and she's a user so... Reference material (from CCS) identifies this model (upper left). Alcohol burner with single vaporizer tube, internal needle and spindle (non-jointed), green bakelight PRIMUS SWEDEN labeled wheeled handle. Steel tin with the little arm clasp to keep the top lid up (presumably to act as windshield with the stove inside of it, as shown in reference and my stove shot from above). The steel tin is in good condition and retains her original colors of olive-brown outside and off-grey/green inside. She still has her PRIMUS label sticker on front top and PRIMUS SWEDEN face plate with wire loop handle front side. Burner has waffled priming material (asbestos?) encircling and tight to tube above the spirit dish, has long angled pilot light with large 'clasp' to support the thick single-tube vaporizer. Bottom of burner has lead washer. Svea 'MADE IN SWEDEN' and 'SVEA No. 774' 2-piece brass draughtshield. Not original to the kit obviously but she fits the burner fine. Internal needle protrudes from jet when turned off much like burner 4155 (spindle all the way CW). No stamping on burner. Outer steel cap labeled PRIMUS METAL SWEDEN No. 4205, 4 rolls of holes. Inner cap with center tube rolled as it contains a seem lengthwise. Single-ended spanner labeled PRIMUS one side and SWEDEN the other. Fuel tank a standard 210 and is stamped PRIMUS No. 210. An impact to the pump tube area has been soldered by previous owner. Pump rod and handle made of brass. and MADE IN SWEDEN Side with A/B B.A. HJORTH & Co, Stockholm Sweden. then the Primus trademark: Sole Makers of the Genuine APPARATUS in 4 languages. Bottom stamping AI 8. No writings on fuel cap, vent screw or center fount cap. Vent screw unscrews but is not removable from fuel cap, fine brass linked chain for 210's of this period. Leg sleeves each have small hole near their bottom to allow water drainage - again typical of this period of No. 210. Previous user had threaded white-rubber gaskets (non heat resistant) over top of the hardened originals, which were removed during the checking/cleaning process. The original gaskets in both her fuel and center fount caps had dried out and were replaced, as was her NRV's original cork PIP. This one with a lead washer, making removal and replacement very easy. Her pump leather was dry but otherwise in fine shape, a dunking in sewing machine oil made her supple and usable. She passed all the pressure tests, so lit her up. Priming Wave of flame enveloping the outer cap as she lights Initial burn Running consistently A very nice stove but can be finicky to keep a consistent burn using 100% methyl hydrate. They have a tendency to exhibit a 'breathing' or 'pulsing' pattern to the flame at higher heat outputs, which can be controlled by reducing the heat. But once the flame is managed properly they are excellent stoves. The case she's packed in, like the Primus 41's, is solid and durable and fits her snuggly when packed. I would not recommend running her inside her case as shown in the picture: not efficient, too confining, scratch the inside case paint up to crap, limit pot size, etc. So either make a draughtshield or use a compatible equivalent from another stove.
