Hi there! I found this Optimus in a pile of rubbish someone was getting rid of. I can't find any number to help dating it. On the top you can see Optimus N°5 on one side, and an inscription on the other side that states in 5 languages (including Arabic at the bottom) "sole makers of the genuine <Optimus> apparatus" with a globe on each side The bottom only states made in Sweden, Here are some photos Thank you!!
Thank you shagratork, Was totally clueless about it because there is no letter coding referring to a specific period. Guess I understand now why it was in a pile of unwanted items instead of a specialised auction site Thanks for your help!
The late Optimus No. 5 stoves are a very good and reliable stove. It looks like yours is missing the silent burner outer burner cap. Suitable caps can be obtained from eBay, such as this or this.
Awwwwwww, thank you guys! Really like this community, has got a lovely spirit Never seen one of these before to be honest so I was really keen to find out more about it Cheers, J.
Hi @Juliet Welcome to CCS. If you require any more information about about how to fettle (fix) your stove, then just ask and you will get lots of help. Kind regards, Trevor
Hi Juliet I think the bottom tank marking started in 1969 when Optimus bought the Svea brand name for liquid fueled stoves. At the time they were making Optimus, Primus and Svea stoves. With that tank marking the same tank bottom could be used on all three makes Regards Bryan
Hi Juliet What does the lettering on the burner say? It can also give an indication of age if it is original Regards Bryan
Hi Juliet This may help you with the burner marking. The article initially does not look as though it affects your stove but if you continue reading you will come to the burner markings https://classiccampstoves.com/threa...-period-of-optimus-history.24548/#post-250225 Regards Bryan
What am amazing article Bryan! You are a well of knowledge!! It must be post 1969, as the stamp fits your description The burner says MADE IN SWEDEN, and again has got the inscription in Arabic It does really make sense that the inscriptions became more and more generic as they took over the different brands Thank you all again for your help! All the best, Juliet
Arabic? I see English, French, Spanish and another language, not a latin alphabet, but no Arabic letters too. Regards Radler
BUMP Above is an Optimus No.5 (no superscript) much has been learned since 2016 that can, as in title, "Help dating No.5" In-particular, another look at the, later OPTIMUS No.5s (&1s), with "made in sweden" bottom stamping. No.5 in OP looks like a match to @Stanisław Grajewski 's beautiful virgin Optimus No 5 ( unused, late production ) he just posted. An excellent reference, thank you. Stan FYI re your "The stamp on the top of flame spreader suggests period after 1962" Yes. Additionally, the next comment estimates your year range to "1967 (or earlier) -to- 1981" re above "The stamping on the bottom of the tank suggests that your stove was made in the 1970s/80s" maybe so but an update to that would be: > bottom stamping indicates stove made "by 1967. could be earlier (/later) > 1975 Optimus Traditional Products Program catalog might indicate details match thru 1975 > tank details indicate stove not made after 81 (changes made by 82). A very helpful on-topic Ref Post: Optimus No:5 1967 , that's right, a hard-dated 1967 No5 (we presume No.1 is same) bottom stamped Made in Sweden [[aside: I dunno what year, for Optimus stoves, the made in sweden on bottom began? For 1963-66 Optimus stoves (not Optimus-made Primus), unclear "to me" what that bottom stamp was (63-66 there was no "need" to change the (Uppl Vasby) bottom stamping on the "Optimus" stoves).]] PS A site search found this "Help.." thread for me. OOPS, sorry. I just now notice it is in the Reference Gallery. 2800 views
