Falkenstein? - Set of mid century hanging lamps

Picked up a set of mid century hanging swag lamps a few weeks ago - total height is 16", width is about 14". Glass with brass top & edging/ designs.
There is a gold colored foil film inside of the glass that is coming loose... will need to be removed/ cleaned, but I've left it in place for now.

I've come across several Falkenstein lamps in the past, but they were all stamped and had a 4 digit number. This one has only "F" stamped on the brass top with a copyright symbol below it.

Did a little reading online, but can't seem to find confirmation that these are indeed Falkensteins.

Thanks!
