Big, heavy Wollensak 15 Inch f/5.6 Raptar Telephoto lens. It is mounted on a 3 7/8" x 3 7/8" aluminum lensboard. The blades seem good. The metal barrel is in very good condition. The lens glass has some haze and about 10 specks of dust? inside. It is probably fine to use but an internal cleaning will make this lens really nice. I see no scratches or fungus. The case is very good. It is lined with a blue velvet fabric. Good lens !
