Coulter Optical 6mm Ortho from way back in the 70's or 80's. Mint condition optically and cosmetically - actually looks new.
Looks like a typical "Circle T" but all I can find engraved on the barrel is "Japan".
The usual Japanese Ortho performance - SUPERB! Includes handy dandy pill bottle storage container.
$40 shipped in the USA. Insurance extra. Certified funds or Paypal plus 3%.
Thanks and keep looking up!
