| Here's the "A" lens for a 61-90-04 bubble sextant, in the original Military issued B&L packaging dated NOV 1945. The plano convex lens is 31mm diameter and 4mm thick with a focal length of 174mm. When combined with PCV "B" lens it acts like a window. The center has a 20mm reticle. High quality optical glass and a rare Military collectible! |
