The L on the base of the tank is of no significance for dating as Optimus did not date code their stoves. It is likely a factory code system used for tracking batch or piece-work production... Best Regards, Kerophile.
hello Yun, Wow! Nice. congrats. re your "I want to know the history of this stove. " Wim guess: First half of the 1920s is my guess. Yun, Not as a counter point to Wim, just sayin': per Trevor's "Hyperlinked Index" on right side of home page, within it quickly and easily find your Optimus 96 detail: the earliest document, on CCS, indicating Optimus 96 is 1929. You can learn more details on CCS re your 96 but it's fair to say re Swedish maker timelines, for ANY model, that is good place to start. ---------------------
I am sorry I have been impolite and not said welcome to CCS 1. The difference in lettering is for all Optimus stoves not just the No.96. 2. The letter L on the underside has an unknown function . Perhaps it is to identify which machine or worker made the stove part. Many Stoves have these letters stamped on tank, pump rod , burner etc . 3. The only manufacturer who had a code system for dating was Primus . 4. I have no detailed knowledge of the Optimus No.96 , I do not own one , I have a very similar Primus No. 96. There are many people here who have great knowledge and can help you .
@kerophile @OMC Thank you very much！ I will reconsider after rethinking. It's fun if there are many mysteries, and it's even better to have friends to share. To everyone in this forum, and to everyone who likes old stoves ... Thank you.
@JUN you are very kind. Because of the translation it would be easier if you could ask specific questions. I think you will find that many people here will be happy to help you . This is probably the best place on the internet for information about classic stoves . If you need help to navigate the website , then I can help you
@A A C You also showed us the cute "JUN". I am reassured by your kind words. I will go to bed first. Have a nice night ... Thank you
Hello everyone！ I couldn't burn it yesterday so I burned it. There were almost no problems with pump cups, filler packing, etc. However, the NRV was firmly attached and could not be removed, and the other was fuel leakage from the joint between the vaporizer and the tank. The packing of the tank is like leather packing instead of lead. Have ever used leather packing for tanks in the past?
If the NRV is functioning , then leave it alone for now. You need a special tool to remove it In the past people used leather packing . Now you should use heat resistant packing . You can buy them here . Burner Washers.Small. Asbestos-free. Pack of 4 - The Fettlebox The webstore is the sponsor of CCS . The owners runs the CCS website. You can get all you need of seals etc from there .
Sorry. I have told you the wrong thing . I misunderstood. The connection between the burner and the tank requires a lead washer . This is much easier to make . You can also buy them at Fettlebox . I am very sorry I mistakenly thought you had Radius 21 and you were talking about another type of burner It is early in the morning here
I also need more sleep! I was so much focussed on the feet I forgot it is not a Primus! Indeed, the first Primus N°96 had the funny little round feet, followed by the later fixed feet like the ones on this Optimus. A couple years after WW1 Primus made the folding feet while the first Optimus N°96 appeared around 1930, still with fixed feet. Anyhow, I like all model 96es! And I am not the only one! A very good read is what Brian Miller wrote down on both the Primus and Optimus N°96s. Links are in the Reference gallery at the top of the pages dealing with both.
Good morning @A A C Thank you from early morning. The old stove had NRV stuck, that was exactly it. I have an NRV wrench, and I tried it but it didn't work. If I try to force the NRV off, it will break the stove. Must be applied with remover or seen by a specialist. After all it is like this for lead packing, isn't it? Thank you for your valuable information.
Thank you from early morning. @Wim If the people who made this stove were still alive, everything would be easily solved. Thank you @Wim
@Wim Yes I still make it in my country. However, the annual production volume is small and the price is very high. On Amazon, 354.17 $ at the rate of US $ 1 = Jap ¥ 120. This price is the same as the price I got for this Optimus 96 second hand. I feel unusual in this situation. Also, the accuracy of Manaslu for the last 20 years is not good. It is getting worse with the change of generations of craftsmen. I lost Manasuru 121, which I got 35 years ago, somewhere. I think it was the greatest stove I've ever used.
So sad the quality is no longer what it used to be! I think this is mostly because of economic reasons, happens everywhere, all the time. I have a nice collection of stoves at the moment, I think I'll stick with them! (One exception, I'm hoping a run down Optimus 111 will make it to my home for 15euros, I'm not complaining! I'll know more in a couple days hopefully )
