Given to me by a colleague from Kiruna, Sweden, back in 1999/2000, the Arctic Rangers Beret which he wore late 60's/early 70's.
No visible markings in the beret apart from a small, white rectangle, the badge fitting which would have been in the "N" position is long broken off.
One of those items that I particularly like as it was a friend's.
