This is a Bausch & Lomb "Sirmont" frame. It's an authentic piece from the 1960s. I acquired it from someone who purchased it as deadstock. The condition is excellent. There is, of course, no oxidation odor. Black Bausch & Lomb Sirmont frames often have tarnished plating or are small in size, but a piece with all these ideal conditions may not appear again. Frame only, no lenses. Lowest price. Thank you. Brand: Bausch & Lomb Size: 46-22 Temple: 5 3/4 #b&l #ray-ban #safety #cross hinge #Bausch&Lomb #safety
