I would assume it's a pretty late model, and if so it would be more likely that it is a 209 than a 210. Also with an original Swedish Nife glass, which is nice. Worked without any fuss with the, for me, standard Peerless mantle.
Nice find Christer. I think I can make out it only says 200 on the tank. That would fit with the red wheel and the nickel top cap. That would put it around the mid 1940s, so not one of the later ones. Interesting it has the varnished handle and not the black painted one. I have wondered when they started using this finish on the handle or whether both were found at the same time.
Ah, thanks Nils! I thought that this cheap looking plastic control wheel was from the 50's, hence my assumption. Yes, the tank only says Optimus 200. Do you know how the parchment shade was attached? I was wondering if it had some sort of springy tabs, or such, because the hood has two marks exactly opposite each other which must have come from removing and reattaching something at the exact same spot:
I've never seen an original shade for a 209 and the catalogues are no help in this matter. The 210 used the standard enamel shade to attach the beaded fringe to, so it shouldn't leave that type of mark. There is always the possibility that someone made there own attachment.
Yes, that is always a possibility. But it would be nice to see how the original parchment shades were attached. Strange that none has survived.
