I made some of norwegian troops. The main problem is that there is almost impossible to get any pictures from the WW1 and upp to 1939. But there is litteraly 100's from 1905. (We nearly had to fight back then)
The army was modern in 1905. (New uniform withouth shiny buttons, machinguns. But we kept the older rifle. (Krag-Jørgen*sen))
So perhaps use the ones with old uniform for before 1912 and the new from 1912 and upp?
Norwegian Old from before 1890 (German style uniforms, but norwegian built rifle(Jarmann))
Norwegian New uniform (1905)
Noregian New uniform n machinguns (1905)
Norwegian Cavalery 1905
The Norwegian Royal Guard (Norwegian name "Garden") (1905 Saluting the New king)
Norwegian light infantry? 1890's (They are "Jegere"(Hunters), better trained, perhaps a little more like the alpine troops? All norwegian soldiers are trained for winter and mountans..)
Norwegian Light inf. 1905
Norwegian light inf. 1905 (In front of a train)
Norwegian light inf. ca. late 20's best I could find so far.
