Greetings from Canada... Hello everyone, I’m a new member to the site, so please excuse my ignorance as Im just now learning about these wonderful old camp stoves. I discovered this Optimus 00 on our local swap & shop website. I have other more modern stoves that I use on canoe trips, but this one must have a lot more history behind it. Can anyone confirm that this could be military ? Where is the best place to find a proper pump knob ? Any help or information would be greatly appreciated as I intended to make it function once again. Can anyone tell me the age ? It has “bun” feet. Thank you - Avro.
