Well seeing as I live in Montana and there could still be snow on the ground for the match the winter one would work if you have pictures!
Well, I think that getting the uniform of a Legionnaire from Narvik (1940) could be a bit challenging for you (puttees, heavy white socks, sheepskin canadienne etc.), but you shouldn't have too much difficulties finding the uniform of a legionnaire from 13th D.B.L.E. from Italy in 1944. What you need to find is US Army "chino" shirt and slacks, M1923 web rifle belt, M 1938 leggings, the Cross of Lorraine sleeve patch on left sleeve, a fourragere in the red flecked with light green of the Croix de Guerre 1939-1945. For the head you use the khaki beret of French Fortress Troops' pattern and you put on it the gold diagonal braids indicating your rank. For example you use two braids for "Sergent".
I could send you the illustration of this man, but I'm afraid I have no idea how to upload a picture let alone make a snapshot of it from the book. Can ask my young friend here, if you're interested, whose more computer savvy than me.
And you better hurry up... Once Obama gets his hands on your weapons, you'll be lucky to keep your meat cleaver or electrical blender.
