Moderators: I may have this in the wrong section if so could you please move it to the correct area?

Can anyone give me information on this pin? This item is out of my collecting area and I know nothing about it. It has the Cross of Lorraine with "France Libre" in enamel on the front. The reverse is unmarked. This first question is: is it a period made pin or a reproduction? The next question is: who would have worn this and in which era would it have been worn?

Thank you,
Hummel
