That pair are 40 years old. I got them back in 1980. I’ve since replaced them with a new pair that looks just like the old pair. I couldn’t get a new temple piece for the old pair. The old pair got lose in my truck and I stepped on them.I've got my wife's grampa's Ray Bans from the fifties WITH THE TAN LEATHER CASE! He had them.set up with yellow lenses for skeet shooting I think, with Rx lenses. I had sunglasses made into prescription lenses. If they ever turn up again I'll have them redone in the progressive bifocals, see if they can do that in mirrored lenses?
