Identify These Vintage Sunglasses?

I’m trying to make a sterling silver replica of these aviator-style
airforce sunglasses and would like to know more about them. Has
anyone seen such a frame before? Take a look at:

Nice aren’t they? The hinges are an amazing example of cold-joining
using pressed metal parts.

Please contact me if you know what brand this frame is.

Thanks
Brian
