Likely a question for the Scandinavians... I have a couple of examples of Primus 1021 and 1031 Carbide Lamps, stamped with Three Crowns and Typ 1 (Type 1). I have recently obtained an unbranded one (I believe a Skultuna but I havent found any literature on them), it is stamped with Three Crowns and Typ 5 (Type 5) on the base. It is made of brass, very very heavy for its size and the two halves screw together. Is there a list or explanation of these Kontrollmark "Typ"s for lanterns? Is it material or feature specific? The Skultuna is nearly ready to go, all the jets and safety holes have been found and cleared, I just need felt for a filter and i'll have it running as well, photos to follow anon Alec.
Maybe you should check out our Admin Christer Carlsson.s carbide lamp site Karbidlampor - en sida ägnad åt vår svenska karbidlampa I think your lamp may be the typ 5 "Erik Sörbergs Armaturfabrik" lamp. I think Christer is better to explain the "Typ" and "Three Crown" marking. /Conny
Conny got it right. If your lamp is stamped "Typ5", it should be a lamp from Erik Sörberg. Not a lamp made by Skultuna. Skultuna was never heavy since they used thin brass or tin sheet. Your "Typ5" you mention as heavy, and that's correct since these are in cast brass. The type number (Type of course is Typ in Swedish) was granted in numerical order by the authorities of explosives as soon as a lamp was approved to manufacture and sell to the public. The three crowns is often mistaken to mean that they should be military, but that is of course not the case. You see that alot on online auctions when regular domestic lamps are said to be military lamps just because of the three crowns... They are just a stamp to prove that they have been approved by the authorities. Carbide lamps from Sweden was a typical crisis thing, and as such, they mainly were made during kerosene rationing periods in WWI and WWII. The Type numbers starts over from one during the WWII period, hence the confusion with different lamps that can have the same type number. Hower, you can see which period they're from by the look of the three crowns. Generally stamped directly into the lamps from the second period, but with loose badges from the WWI era.
