I feel you have an extremely interesting Revolver. I'm not sure it anyone has mentioned this yet, but both the Germans, & the French Millice are known to have utilized numerous Allied arms obtained primarily from captured 'arms drops' by the British S.O.E. & the U.S. O.S.S.. Amongst the captured weapons used were Sten SMG, S&W & Colt Revolvers, M1 Carbines, & assorted others. These 'drops' we're initially intended for the French 'Resistance' Forces, but many times were captured intact by the Axis Occupation Forces.
