Hello fellow fettlers. I have just bought this Primus No: 501 (see pics). A new valve and new gaskets for the filling lid - which by the way is in an odd large size/diameter compared to all other stoves in this category and age - and she was running fine - incl. the adjusting mechanism. I have not been able to find any information on this Primus No:501 - can anyone help me regarding age etc? (In case this info is already on this great forum - I apologize) - Best regards and merry flames to you all.
G'day @Harder D. Soerensen and welcome to CPL. I think this is a rare stove as there is no others listed in the reference gallery. There should be a date code stamped in the bottom of the stove. Have a look at his post https://classiccampstoves.com/threads/primus-dating-chart-1911-1963.11464/ The stove is shown in this catalogue dated 1914 https://classiccampstoves.com/threads/1914-primus-catalogue-no-371.13644/ and this one dated 1917. https://classiccampstoves.com/threads/1917-primus-no-492.32573/#post-33260
Thank you so much ROBB055. You are right about the stamp - it is an “A” (I get a “no permission to open your two catalogue links?)
WELCOME Harder, What a fantastic 1st post! (candidate for gallery @shagratork ?) I am +1 w/ROBB and now you see that it is a 1911. Re size/capacity the "Oljebehallarens rymd 1.2L" has your 501 at the same size as 1911 No.s 1 & 5. I encourage you to subscribe to access the catalogs. That said I'll insert relevant pages (not sure I have permission to repost ref. images, if mods want to delete this that's fine too, seriously). for all I know it is a 1st on the site, I don't recall either a 501 or that original early regulated roarer R135 both are sweeeet ! well done thanks for posting, omc fyi for search R137 is early regulated silent
@OMC - Thank you very much for the kind words! I have a small collection of old german alco-burners, Danish Ginge, Spanish Hippolito, one of the first Radius camping - and some primus/optimus ;-), so I am very happy to be included in this great forum! This 501 caught my eye, since I couldn’t recognize the regulator. The number 501 wasn’t mentioned in the ad. So I thought - for 17 $ with postage - I couldn’t go wrong :-)
I have already moved it to the Gallery. But we might perhaps need a new category for the 501 models, which is a thing for Ross to create, so I have alerted him to decide.
Thanks Harder! I think you have taken pretty many good pics of different details already, but we like to see all possible details in the reference gallery, so additional pictures are always welcome.
Certainly have. Excellent close-ups of a rare stove. Brilliant, and welcome to CCS @Harder D. Soerensen John
@hikerduane and @presscall - Thank you. I don't think this has been used for a long time. The leather cup was very dry/hard, and when I unscrewed the rod, the leather literally just smouldered. The NLV couldn't hold pressure, so I changed it. Tried to fix the old valve but again the NLV-gaskets just changed to dry dust. I managed to fix a new gasket for the filling lid, but I need to find a gasket for the airscrew. Will try my local plumber. All these bits turning to dust - I think the same faith hit the fiber-wheel. It actually burns quite fine for a 106 year old stove. I also have a new Primus 111R - but this old stove is actually easier to regulate the flames on. I have yet to find one on the internet (Ebay, auction houses, yellow pages etc). The only place I found info was here on this great forum!
all, My thanks again to Harder for this excellent example of a No. 501. To aid search I added R137 silent burner into text above. I should have added the 505 stove aye, . Credit goes to abbahco1's continuing his decades of contributions to the rare content found only on CCS . Without his posts I would not have (& could not have) made the connection to 505s in SRG. Both 505 examples happen to be 1914 btw. thx omc tag primus 505, primus no. 505 @abbahco1
