extremely rare original pair of collar tabs for a member of Marechal Petain personal security Detachment.

Unit was created after the fall of France in 1940 and was terminated in 1944 during the liberation of France. 
Approximately ~1000 members at its height. 

the best reference book in my opinion on the subject: La garde personnelle du chef de l'Etat 1940-44 : by Xavier Aiolfi      published by Nouvelles Editions Latines  in 1999
