Made to store away as small as possible, this is a marvel of hand tooled telescoping tubes. Pull out all the way and focus by adjusting the smallest eye-section. Feel like a sea captain scanning the horizon from a heaving aft-deck. Nickel plated. Nickel finish was more for civilian use, since captains and military didn't want to become an obvious target for snipers in times of action. Magnification is 3x.
