Bausch & Lomb 8.25 F 4.5 1:1 MAG Oct 5, 62.  This camera lens has the capability to make 5x7 negatives, and high quality photos. Those old schooled, vintage landscapes and portraits obtained high resolution and classic photos using this format. This is a great lens for the collector! For the telescope builder, would make a great small telescope objective lens. It comes as is, and priced very reasonable.
