I have recently acquired a pair of Mk VIII goggles to go with my leather flying helmet. They are genuine issue goggles and not reproductions. I've tried to research how to tell the difference between wartime manufactured goggles and post war goggles as this model was used for many years after the war. However, I am drawing a blank. Is anyone here familiar with the subtle nuances of wartime and post war goggles? I've noticed that some goggles have black thread holding the padding to the metal frame whereas mine have a tan thread. Perhaps that's an indicator but it might also simply be a manufacturer's variation. Regardless, they are in beautiful condition and came with the issue box.
