In my stash of relics, I found this incomplete Svea 121 of late Optimus manufacture. It also did not have a correct pump rod. So I decided to make it complete by fitting/replacing the missing/wrong parts. What I did not notice from the beginning is that the pump tube has been replaced with a larger diameter one, so the spare 00-pump rod I had does not fit. Instead, the pump rod from an Optimus 45 fits. The stove seems not to have been used, but I have no record of why the larger diameter pump tube has been fitted. Possibly someone in the old R&D team just played around practicing soldering or something. As found: Burner marking "Optimus Sweden" (so probably later burner) and flame ring marking "Sweden Sweden": Stamping "Made in Sweden" on bottom of tank: Pump rod from Purgatory or something. It has a brass lid, but aluminium rod and plastic knob. Next to a Optimus 00 spare pump rod: Traces of solder job: Fitted with the few parts missing. I'll have to find a spare No. 45 pump rod to make the stove complete, the reserve lid has to fit somewhere when the stove is assembled. I'll make my mind up later if I should light it or keep it as is.
