I have attached two photos. IMG 8895 is a view through the Kollsman periscopic sextant and 8887 is a view through my Pioneer A-7. Some bubbles in various octants are opaque as in the A-7 so you line up the body with the side of the bubble while others are clear and you center the body in the bubble.
