Need Asssitance in Identifying Vintage Aviator Sunglasses

[Bogie1943]

Hello Ladies and Gents,

I picked these up on eBay a while back thinking that they were from sometime during the 1930's. I am unsure of the maker or where they originate from. Rims are metal and the lenses would appear to be glass. Very lightweight and the glasses seem to be meant to fold up. I need your help experts!
