I have one of those counters too. The one listed is missing a tube and its front lens. The lens will be hard to match if someone wants to restore it correctly -- it's a dark amber circular polarizing filter; the few places that can supply this material call it HACP, and they charge an arm and a leg for it. Best bet is to rob one from a similar piece of equipment that's otherwise in worse condition, or just go with plain tinted acrylic.
