This one’s a little obscure, but horrifically esoteric. (I think. Maybe it’s the other way around)
Anyway, could anyone point me to a good resource on what Norwegian Army (or Home Guard, even) uniforms looked like, circa 1965?
Summer wear, in particular, if that matters.
Not quite what you want, but this page has a link to some 1965 pictures of British forces on joint maneuvers with the Norwegians. Most of them are of Brits, but a couple look more like Norwegian uniform to my untrained eye. Sadly, they all seem to be winter shots.
Starting with photo #3 this page has good shots of the Home Guard 
on one of their more important missions. I doubt the uniform has changed since the mid 60s!
