new old stock. looks like 1951 is marked on stamp inside of the pants. these are similar except long pants to shorts i have from france, so i suppose is for the same purpose, french foreign legion pants. button fly, fabric is not listed but it is 100% cotton. button fly, 2 inseam front pockets. 2 back pockets close with flaps. single pleat .1.75" waistband, 1.8" belt loop. hand measure waist is 37" so i suppose can fit 35/37. inseam =31". opening at bottom  =20" all around. pants can be hemmed if need to be shorter.,1.5" on inside of pant can be let down, appears it is the same color to me. the pant is marked 35.

FROM A FRENCH CUSTOMER KIND ENOUGH TO  GIVE ME MORE DETAILS ABOUT THE PANTS"It's pants "modèle 48" (M48) fot the french army between 1948 and the 70's. This include the foreign legion but was for all the army in fact.

The sizing is the old french military system wich is no more used. The 35 is to be read 3 and 5. That's means waist size 3 (roughly a M or L) and long 5 "
