Thanks for the link. My long-lived stove was a Primus 71.

Its tank had a very slightly larger capacity than the Svea and the total weight was a couple of ounces more.

I replaced it with a Svea 123R "Climber" which added the self-cleaning needle. The Wikipedia article notes some complaints about this innovation. Put me down as a complainer. It wasn't as reliable as the Primus. I wouldn't recommend it. Get a non-self cleaner if you must use Svea.

Also, I think eventually, the wicks on these stoves need replacement, but it's just my theory as to why their performance eventually degrades (I remember early Fletcher editions making vague mention of this degradation, without offering reasons).

Sad to say, good old MSR (and maybe the copy cats) eventually blew them all out of the water and unto kingdom come.
