An older Primus No 1. It has the older looking legs and the 'F.W. Lindqvists Patent' on the pump cap rather than the 'Primus - Made in Sweden'. The tank lid does not only say 'Patent' without any number as these flat, early ones often does, but also No 4028. (That is not an actual Patent number. At least not a Swedish one.) No text on either the air release screw or the flame ring. The cast iron top ring has the spare parts number R578 at one place, but also the letters 7-03. Can it be a date? July 1903 is not an unreasonable dating of the ring itself, and probably not of the stove either. It's obviously some years older than the magical 1911-limit.
No Yonadav, this one was not sold on eBay. If it had been, I'm quite sure it wouldn't have been in my possession now. Do you have a link to that one? Would be interesting to see how it looked. I'm very interested in the different appearances of the Primus stoves that was made before 1911.
I too like the early ones. The Primus 'Kosmopolis' jubilee book revealed the PRI-MUS logo with the picture of the stove in the middle of the word was used on product after 1896 which helps a bit.
Thanks Ross! I need to read better in that book you so kindly gave me a while ago. I never remember stuff like this in detail. This would mean that my stove is older than 1896! I wouldn't have guessed that. I thougt they had the earlier tank at that time. The kind of tank the 1891 stove in that very same book has. My stove has the 1896-patented NRV by the way, but I would assume that Primus used it a while before the patent was published.
Silly me! Of course mine had the PRI-MUS logo with the picture of the stove in the middle of the word. I don't know what I was thinking... One relevant question! Do we know when this bulgier tank replaced the more plain looking first one?
Sorry, Christer - I did not keep a link to that eBay auction, and the UK eBay does not let you search for past auctions. Yonadav
Thanks anyway! About eBay! I don't think they removed the possibility to search for older auctions. There's still a checkbox for completed listings under advanced search. But for some reason, you can't choose to search both title and description when you want to check the completed listings. And you also has to be logged on to be able to do this...
Hello Christer. I wonder if your stove was manufactured in 1900. The reason I say that is the "0" stamped near the edge of the bottom of the tank. I have 2 pre 1911 Primus No.5's - one with a "6"(no feet on the legs) and the other later one with a "J"(tenth letter of the alphabet = 1910?? and with feet on the legs) stamped into the bottom of their tanks and both have the same pot rings with 7-03 stamped into them. I wonder if the pot rings all came from the same casting batch. Cheers, John
Hi John. Good observations, but I don't really think that this little stamping is the number '0'. It doesn't really show on my picture, but that little indent is a perfect circle, and both the number '0' and the letter 'O' usually has a more or less oval shape in these matters. The use of a 'J' in 1910 sounds a little bit far-fetched. Especially if they practically immediately thereafter took the descision to start over with an 'A' the next year when they started with the known code series. There are often some single letters here and there, and it's hard to know what they really meant. The pump knobs e.g. often has a little letter. This stove has a 'K'. Another one has what could be an 'L' or perhaps a 'V'.
OLD THREAD alert Christer, You are "...very interested in the different appearances of the Primus stoves that was made before 1911" No hurry, as this posted 2010. I'm curious re the roarer and have some comments while I'm here. Please share any update or current thoughts re your dating of this stove. I do not know and I post to ask you: Do you think roarer is original / correct for the age of the stove? (or not). Thank you. My comments, please do correct me if I'm wrong. I note your opinion Primus likely used their internal NRV, prior to the patent *No.7225 being granted 1896. I previously thought use of PRI*MUS logo and No.7225 NRV began at same time (after 1896), that was convenient, but that may not be the case. (*surprised to see CCS search w/only 2 hits for No.7225) Factors applicable to this one (w/some recap): Increased tank size (bulgier). A No.1 with "Patent" on tank. 'F.W. Lindqvists Patent' on the pump cap. No feet. Lastly this unique flat tank lid albeit with "Patent No.4028" it fits among more common *flat lids with "patent". About that, in addition to yours and only pre-1911, tank lids w/different text are more than a few: > B.A. HJORTH & Co. PATENT STOCKHOLM > like line above w/backwards N, > AKT.BOL. B.A.HJORTH & Co. PATENT STOCKHOLM > AKT.BOL. B.A.HJORTH & Co. PATENT Stockholm RE Pre-1911 air screws: air screws w/o text are earlier. Air screws may have developed in similar sequence as tank lids (same may be said for pump lids) FWIW re two examples 1911 tank lids: > AKT.BOL. B.A.HJORTH & Co. PATENT Stockholm (same as last line above) and > AKT.BOL. B.A.HJORTH & Co. Stockholm thx omc tag @Christer Carlsson
Hi OMC. My remark about the possibility of them using the 1896 patent for the NRV earlier was in relation to my mistake that the stove was without the PRI-logo-MUS text. I corrected that miss in my thoughts in a later post. However, it's still possible that an invention could be in production slightly before - or after - the date the patent was granted. It's not an exact thing to use fore dating. I couldn't tell if the burner is original to the stove. Especially since the stove can't be exactly dated. But I generally assume that the burners have been changed at some later point since they are more or less a spare part that is worn off by regular use. The mirrored N you often see on the flat lids is a funny detail. I always assumed that someone in the production line just simply mixed up a cyrillic letter 'И' with our latin 'N'. Russia was one of our largest markets back then before the revolution, so cyrillic letters was of course often used.
