15 Solid Brass Hand Held Telescope – Pirate Spyglass with Leather Case This nautical spyglass is made of brass. The telescope, when fully extended, is about 15 long. It comes in a leather carrying case. The telescope does have some imperfections in the finish, such as tarnish or scratches. The telescope is modeled after older style scopes. To focus the telescope, you need to fully extend the body, and then slowly contract and expand the eyepiece portion only. The telescope will make a great pirate accessory.
