Bell & Howell Co Comat 0.5" f/2.5 Vintage 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. It appears to be in good shape. 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.
