This is for one lens, and you choose the quantity you'll want. Upon the initial listing, I have 6 in boxes and one unboxed for a total of 7 available. Make an offer for all if you like. I'll combine shipping for multiple. These were made in Chicago's Motor Row at 1458 S. Michigan avenue as an aftermarket replacement by a company called DoRay. For decades, they were a lens supplier for cars, trucks, stop lights, fire signs, etc.
These fit all Chevy cars in 1960 and 1961 except Corvair. The base is 3-7/8 outside diameter, mounting screw holes 3-1/2 center to center, the inside diameter of the cone base hole is 2-1/2 inches. The boxes had storage wear (dirt, water marks etc) but the lenses are all perfect and undamaged. Unless you specify a certain box, I'll pick any box and ship to you.
