This enamelled post-1963 Primus No.535, is one which was manufactured by Optimus and uses their equivalent of the Primus No.8155 kerosene/paraffin burner. Front view showing the ‘PRIMUS’ burgundy front panel and detail of the regulator control knobs. Close-up of the front panel showing the pump knob and ‘A B BAHCO’. Overhead view of the stove and the nicely contrasting speckle-green enamelled top rings. The stove fuel label, a little worn but still legible. Side view of the 535 showing the ‘SWEDEN’ stamp which is also on the opposite side. The two holes on this and the corresponding side are for mounting a ‘Top Rail’ (Part No.1136) which was available as an accessory for this stove - shown in the 535 section of the 1967 Primus Trading AB catalogue No:16700 (courtesy of @Spiritburner). This picture shows the regulator control knobs’ offset to the front face of the stove. The 3⅞ pint/ 2.2 litre capacity brass tank - 4 hours burn time with both burners operating. An SRV incorporated into the filler cap - since the 535 uses regulated burners. Primus Metal No.4205 outer caps fitted. The characteristic Optimus 9-hole inner caps are also fitted. These are actually shown in the 535 section of the 1967 Primus Trading AB catalogue No:16700 (courtesy of @Spiritburner). Straight-through punched holes - the signature of a regulated Optimus burner. With the top ring removed, the two holes into which the top ring’s corresponding underside lugs locate, can be seen. The underside of one of the top rings, showing the two opposing locating lugs. Fuel jet and cleaning needle (left-hand burner). Unlike the 535 alcohol model, this kerosene/paraffin 535 has an igniter fitted to each burner. The clipped-on wick can be seen attached to the top of the igniter. One of the two igniter wicks. Each igniter is secured to its burner with a ‘U’ shaped steel rod, looping through two holes towards the top of the igniter which are then located onto two of the burner tubes. Underside photo of the 535. Close-up of the burner blanking plug. As can be seen, no date stamp on the clip. More photo’s to follow…
