Vtg Original 1980s REVO 1204 Monterey Sunglasses Black Frame Grey Glass NASA LMS

These are true original vintage 1980s REVO 1204 Monterey Sunglasses Black Frame Gray Glass Lenses RARE, Hard-to-find! These are not the modern reproduction version that was created. These are the authentic vintage original sunglasses that are highly collectible due to their rarity. They are owned by a friend who personally purchased them brand new so I am 100% certain of authenticity, age and the quality of how they've been cared for. They are in excellent condition; and come with the original case. There is a little squeak sound when opening and closing the right arm. I don't see any integrity issues or flaws.
