Bell & Howell Super Comat 0.5" f/1.9 D Mount Movie Camera Lens. Hard to find lens from a huge estate collection. It does need to be cleaned a bit as it has been sitting in storage. Appears to be in good shape, but I am selling as untested as is. The person who had this had a very unique large lifetime collection so I will be listing other related items. Thank you for looking and don't miss out on this great find.
