I've got Hasag 242 (year unknown). On the pump screw-on cap is "made in Sweden", so seller was thinking that it's Swedish lamp... I had great hope for Primus or Optimus. TAfter close inspection I can see that cleaning needle is missing, excenter by control cock shaft is broken and the glass was finished by Postie... But the biggest thing, which is missing, is mixing tube with whole unit, including burner. Q: -- are Petromax 150/250 parts suitable? The thing, which makes me really happy: the top cap was missing too, but I've bought in DIY store a "magnetic bowl" -- small stainless bowl with magnet glued on the bottom side. It prevents the nuts and bolts to get loose, it may be attached to some heavy iron on the bench, or to the car's mudguard, if you make something with car. It's a bit over 10cm dia. and shape has almost proper... I also have investigated the pet shop -- some bowls for cats look promissing... The lamp come to me a bit yellowish -- nickel oxidized a little. On the pics is the lamp after meeting with felt disk and polishing paste.
