This listing is for a vintage Lumen inc projector lens. This metal lens is very heavy at 8.8oz and feels very solid. It reads “16mm 2 inch f/1.6 Lumen, Inc. U.S.A.” There is dust in the lens but I can’t see any scrapes or mold, there is wear to the coating. It measures approximately 2 ¾” long and 2” diameter
