ZOOAN

• Production era - 1938-19??
• Code number - 16495
• Type - Short, chrome focusing mount for Hektor f= 13.5 cm 1:4.5 with Visoflex I
• Variants
  • Black and nickel, no baffles
  • Black and chrome, 3 baffles
  • Chrome, 3 baffles
    • "The black ones have brass focusing threads, which are very bright and polished. I can see why they added the baffles. The all chrome ones have light alloy focusing threads, which are dull in finish. So maybe at some point later in production, the chrome ZOOANs also were manufactured with only one baffle." zeitz - per forum discussion [3] below
