FLEA MARKET FIND- OLD GLASSES

I FOUND THIS ITEM AT MY CHURCH FLEA MARKET. I THOUGHT IT WAS A COOL ITEM SO I BOUGHT IT. THE ONLY INFORMATION I HAVE IS FROM ON THE GLASSES. THE SIDE STEMS SAY FRANCE ON ONE. THE OTHER SAY LAMY. THEY ARE ACTUALLY IN GOOD CONDITION. JUST CURIOUS IF ANY BODY WOULD KNOW WHAT ERA THEY ARE FROM. THEY REMIND ME OF OLD AVIATOR GLASSES. THEY ARENT SUNGLASSES. THEY HAVE A STRONG PRESCRIPTION IN THE LENSES. THE LEATHER SIDES ARE IN GREAT CONDITION ALSO. THEY CAME IN AND OLD SILVER GLASS CASE. ANY AND ALL INFO WOULD BE APPRECIATED. THANKS.
