I'm trying to trace the developmental history of the SVEA 123. I know that the 123 is a derivative of the 71, but what part does the Campus 3 play in all this? I believe that at some point, Primus either acquired Sievert or they merged to become Primus-Sievert. Is this correct and was it before or after Sievert began marketing the Campus 3? It appears that the 123 came about as a result of developers looking at both the 71 and Campus 3 and they put them in a candlelit room together with some soft music, silk sheets, and champagne and then waited to see what would result. Am I correct here?
Watching with interest. Sievert made the Campus with no affiliation to Primus. And Sievert made the 123 with no affiliation to Primus. The affiliation came later when Optimus bought Sievert Svea in 1969.
If Primus and Sievert joind in 1966, it was not short-lived. The package of my Primus Himalya Multifuel from 2003, was marked Primus and Sievert, that is 37 years later.
@Kent Vining With all due respect, re your: "I'm trying to trace the developmental history of the SVEA 123.

Am I correct here?" emphasis on my intent is, respectfully: re your "Am I correct here?"... there is a lot missing. note: Primus acquiring Sievert (propane portion) is not applicable to topic (and complicated). Re your "It appears that the 123 came about as a result of developers looking at both the 71 and Campus 3..." "Campus 3": (predecessor to the Svea 123) yes yes of course. Primus 70/71: ahh, no. No need to point out only the P70/71, there were many. re your "I'm trying to trace the developmental history of the SVEA 123." [it's all here] developmental history.... not entirely sure what you mean. I often speak of model development, note specifics of an earliest version then note subsequent specific changes (often many changes) that are made over decades. <-- that and understand the reason/purpose driving the changes. IF your focus is... How did Svea develop (come up with design) for the earliest version Svea 123 ? 1952 or earlier post WW2 (WW2 the industry paused). You could compare it with the Primus 70/71, if you want to, BUT not only that make/model. There were MANY similar small petrol stoves on the market for 25 years (pre WW2) before the Svea 123 came out. There were more than a few successful sm petrol stoves out before the Svea Campus 3 (and at that time, pre WW2 pause). As mentioned there is MUCH MORE to the his-story, I will share just a few items Svea was aware of (long) before launching their compact petrol stoves, the Campus 3 /Svea 123: > the integral cylindrical pot support of brass. Credit kerophile for that point: Monitor Minor from early 1930s. <-- that on topic ref. thread will be enlightening for you re the 123, read top to bottom, please. > several weaknesses emerged on earlier makes/models (incl. Campus 3). Svea able to avoid same mistake(s). eg. for one, wider base (larger fuel capacity/more stable) was a plus. Note my earliest Svea 123 example in link above. It's likely that the Svea 123 design would need to function superbly not only stand alone (meet/beat competition) but also... > beat the competition when paired with a small cook set (the "all new" Sigg Tourist !) <-- paired w/cook set was definitely a competitive niche that Svea had their sights on and would soon dominate ! (made the competition rare/obsolete incl P71 cook sets). ---------------- Kerophile mentions German makers (pre WW2 petrol design/engineering). I add to that, that Gustov was a major contributor (Juwels), and self-made original, vs a copier. He was one innovator (there were others), who had the shoulders other stood on. tag @kerophile
Thank you. This is the answer I was looking for. I'm well aware of the myriad of stoves and iterations of a basic design that has its origins in the late 19th Century. The confusion comes from trying to decipher the labyrinth of Corporate acquisitions and mergers that occurred once the patents ran out, the sometimes-incestuous relationships between them, and the fact that today, for all intents and purposes, one corporate entity controls the survivors. My error was the assumption that Primus-Sievert occurred 10 years earlier than it did.
