Bob Saunders Posted November 8, 2021 Share Posted November 8, 2021 I mentioned this here and have had it a long time. Tube with green target lens no markings. Possibly a surveyors instrument part. Green target that rotates. I coupled it to my phone and then did a grey scale image. Any ideas on maker or use? Link to comment Share on other sites More sharing options...
Bob Saunders Posted November 12, 2021 Author Share Posted November 12, 2021 I removed the screw and cleaned the optics and dirty barrel lube. The screw hold a piece in the groove for focus. Then stopped by a survey company, and found it not used in that field. He thought maybe industrial or military? After focusing I can read the numbers on the first 46 KV power pole way down.
