This unfired 350 cp model has the stampings on the fount designated by the Swedish military. That being a "crown" with the letters CF underneath. Bob
Hi Karli, That must be like in the USA we had "Civil Defense". I have an Optimus 1350 with the same stamping. Thanks for the clairification. Bob
Karli , Right, but I don’t believe the CF is an abbreviation for the English word Civil Force, but for the Swedish CIVILFÖRSVARET. /Conny
A small correction, but this is from the Danish civil defence. The Swedish civil defence used a shield with a diagonal cross on it as their symbol. The Danish CF used a lot of Petromax 828s as well as a number of Optimus 1350s. They also had Tilley FL6s and AL21s. It is also possible to find a Tilley X246, but they weren't as common.
