Vtg 60s Eyeglasses Frame Italy Square Full Rim Brushed Silver 52-20-135

Vtg 60s Eyeglasses Frame Italy Square Full Rim Brushed Silver 52-20-135 The engraving has faded a little and therefore difficult to read. I think the brand is M5 by U.I.I. ? The hinge is not spring loaded and therefore does not snap close when you collapse the arms. But it moves smoothly. Really great, clean vintage condition. This listing is for the frame only. You will need to install your own lens. No original case. A general hard case will be provided to protect the frame during shipment.
