This lamp was purchased at an auction held near Boden, Sweden a couple of weeks ago. I don’t think it was a lamp used within the Swedish civil defense system. There is no sticker or residue from one now gone. Perhaps it is one meant for the Swedish army. A number of things at the auction came from the estate of someone who had been a civilian employee of the Swedish military – in Boden. His job title was probably “Auditor”. I can smell fuel when I open the filler cap. The lamp doesn’t look like it was exposed to heat for any length of time. Maybe it has never been used? I’ve not tried it yet. I won’t until I’ve had time to check it more. This 200P looks about the same as the one posted by Christer Carlsson. Would that mean this lamp is one that was made in the mid 60s?
