Hi Folks, Finally getting through some of the stalled projects What we have here is a Primus No.54 stove, sold as a No.154/3 Heater, with the copper reflector (reflector type 3, the "/3") and embossed aluminium tank heat-shield. It is shown in THIS 1935 catalogue as part of THIS illustration. The stove is an X7 1933 model and was bought fairly locally from a dealer who didn't know its history/where it came from (I think it was doing the house-clearance rounds actually). It needed nothing other than a really good clean, the burner a blast-through, the NRV pip replacing and cup oiled to fire back into life. The patina is fairly even, it will get a light oiling and that suits me fine The reflector is in good condition and un-dented, likewise the heat shield. What I did have to manufacture was the support for the brass heater bell. This took a little head scratching until I bit the bullet and threaded some 6mm round bar M6 coarse for a retaining nut and then shaped the rod around, following the contour of the bell. Height, I asked around a few folk with heaters for a nominal height but found varying distances. I settled for nominally the centre of the reflector, I can always shorten to angle it up a little. I put the reflector in this orientation for easy access to filler/vent and pump Full-whack the tips of the flame-cone just enter the heater bell, I reckon it's ok and certainly belts out the heat! Stove-wise, I sourced a set of feet the right shape/length and electrolysed/painted an old trivet to complete the set. Legs are a little shiny but hey, If I find a nicer older-patina set, I'll use them instead. It runs beautifully and boiled 2L of water in a wide pan in under 6 minutes, equating to roughly 2Kw power. Possibly nipple undersized, unsure but I'm delighted with the way it runs. Brian @kaw550red gave me a travel-cap so I could dismantle and transport in a case (Project Pt2, anon), but I haven't had the nerve to disturb the taper seal, this is to me the one flaw of the "50" series, give me a replaceable seal instead of relying on a taper for repeatability. A really nice combination, the heater will see use this winter. Alec.
