U-Boat Red Tinted Goggles.
As worn by the U-Boat crew men, these are a nice pair of red tinted goggles.
In great condition, complete with carrying pouch, these were worn when the main lights went out.
Makers name: Auer, Neophan.
These were needed for the U-Boat crewmen, to adjust their eyes to the darkness.
Forgot I had these.. so small in it’s pouch!
I don’t think these are rare to be honest.
