Ah, the cherished SVEA 123, my 1st backpacking stove and only one for twenty years. I changed to an MSR Dragonfly for it's simmer ability & remote fuel container so I could bake stuff. Now I only use the Dragonfly for winter.

But if you DO get a SVEA 123 be sure to get a detatchable pressure pump to avoid the hassle of priming with a candle on the bottom of the stove.
