Vintage Persol Ratti 649/3 Sport 54mm Blue / White - Silver Mirror 

extremely rare pair of Persol 649 sport sunglasses With glass silver mirror lenses. Lenses are in great condition. And have original lens etching. Some of the barrels of the melflecto stem system move but don’t fall off. One of the screws also appears to be aftermarket, and that hinge is harder to open than the other.
