I just got these in on trade but are a bit too tight on my head. Selling for $280 shipped conus. They appear to be new in box but the box is missing the original label. These have a very cool looking matte black frame with light tortoise and super reflective chrome iridium lensses with '1973' etched on the lens. Very rare pair for your collection (only 400 pairs made) and only sold at Murasaki Sports stores in Japan.
