This is a Primus No. 5. I have dated it to 1910 as it has the features of the first date-stamped Primus Nos. 1 and 5, but is not stamped "A" (1911). Thanks to @igh371 for pointing out that this stove was for sale on Australian eBay., and for subsequent discussion of the stove. "Primus No.5" "Made in Sweden" "Trade Mark/Primus" "Primus" on one side of the air release screw. Circular stamping: "BA Horth & Co Stockholm/Made in Sweden" "L" on tank base plate. "AKT. BOL. BA Horth&Co. Stockholm" Note the legs are the same as the 1911+ Primus stove legs. "V" stamped in a circle. "Primus Made in Sweden" "Z" Note that there is no slot cut into the bottom nut on the pump cup fitting. "Primus" R578" The repair I did (a la @presscall) to the one crack in the cast iron trivet. Up and running Not bad for a 110-year-old stove! Cheers Tony
Great presentation, Tony - this is why I like this site: for the expertise of its members and for these kinds of interesting photo galleries. I have a B & C No. 5: identical to yours, each with a 578 cast-iron trivet and also with the spirit cup on top of the tank for "auto" lighting. Cheers, P
@ROBBO55 The burner came with the stove, but was missing its inner burner and cap. I fitted a 6-hole Optimus inner burner cap and NOS Primus top cap. Thanks, @abbahco1. Cheers Tony
light green flame Shows the resurrection of this burner. A stove that has lasted 110 years is truly amazing.
