Thanks for the links, guys. I really should check my own library more often, though. :oops: Just found my copy of Blandford Press' 'Uniforms of the French Foreign Legion' by Martin Windrow. Lots of colour!
From what I can determine, Dumas is probably wearing the white fatigue blouse and pantalon-culotte or native seroual trousers. He also wears the typical kepi, blue waist sash and cheich (scarf).
The commandant would appear to be wearing the standard khaki officer's tunic with 'mastic' coloured breeches and (non-reg?) leggings.
Here's a hard one, though...any idea what his medals could be?
Cheers,
Mike
