hello,
Your french is too bad but my english is poor, my taylor, also !
You have a picture at this link :
It is the badge of "Hôpital de campagne Hadfield-Spears" or
"Ambulance Hadfield-Spears" in the book "The Free French and their badge" ( a book in french ).
I hope that you understand ;-)
Happy New Year !
Alain Le Floch
