Hello, I bought a Primus No 2 last week. I think in rather good shape, the only two parts missing were the air screw and the burner ring for the roarer burner and maybe an cast iron trivet.The pump is not original and there was a silent burner included. But, after the first cleaning I am not sure about the date, look at the different pictures and make your opinion please. I thought with the early ones the dating letter should be visible inside the inscription beneath "made in sweden" at the bottom. There is not such a letter, that is to say there is one, but somewhere else on the bottom. I am pretty sure is is a capital C, that should mean the stove is from 1913. I managed to get the NRV out after soaking it for two days , tool in a vice and stove in both hands, easy does it. In order to clean the riser tube and the fitted burner, how do I safely unscrew the burner from the tube? The burner tube is round all the way, no hexagon on it. Regards, Ton.
Hi Ton, @ton visser the photo, showing the underside of the fount is not very clear, but it looks like there is no letter stamped under "SWEDEN". This will date your stove as pre-1911. A clearer picture of the spirit (pre-heat) cup can also tell us something as the shape changed early 1900s. Groetjes, w!m
There is absolutely no date inscription under SWEDEN On one of the flat sides of the hexagon I found the inscription XF. Ton.
Interesting! Thank you for posting. IF we can follow details of the No.1 & 5 timeline? it is pre-1911 and your feet on the legs places it about 1910. Yes, the pump asm is replacement (a Sievert, looks like) and i "think" filler cap is also a replacement. Noteworthy your large No.2 roarer is round at base, no hex. I dont expect that detail to be a confirmed dated detail... for the No.2. With way more pre-1911 examples, the round base of No.1 roarer burner "should" be very early in timeline. Caveat, plenty of No.1s, not so many with original roarer burner. Myself, I do not know what approx year Primus began using the hex fitting at bottom of No.1 roarer?
Ton, I'm having a closer look at this, the bottom of your roarer burner has hex fitting, yes? ------ @igh371 Ian, i read "The burner tube is round all the way, no hexagon on it" ah. burner tube , my bad?, burner tube which is the rizer? I try to zoom in at the bottom of the roarer burner, i cant make it out but, now having looked as close as i can.. .it probably is hex at base. oops. Re OP, are you too thinking this is about a 1910 ? btw do you have a year range Primus began using hex base on No.1 roarer?
Starting from the top of the tank there is a round tube all the way up to the preheater cup. Just above the preheater cup you see the hexagon, ment to put a spanner on in order to screw the burner into the rising tube, rizer tube or burner tube if you wish. No, I do not have such a year range. And I would like to unscrew the burner from the rizer or burner tube. Having no flat part or hexacon on that rizer or burner tube to hold against made me ask it.
