Old goggles vintage flying goggles collectors RAF goggles

These are vintage goggles but apart from that I do not know much about the item! They are very old and as you can see from the photos they are not in great condition and the stitching is coming un-done. I assume the goggles are flying goggles but I am not sure.
If you have any questions, please email me and also check out my other items,
THANKS!
