jonty Posted 2 August 2019 Share Posted 2 August 2019 I am having ongoing problems with my sight picture which is getting worse. Ive tried lenses and most other things, so I would now like to try or buy, either- Gehmann Cylindrical Lens System Part No. 579 OR Gehmann Optical Correction unit Part No 50300-00 If you have one not in use or know someone who has, please send me a P.M. Thank You Jonty Link to comment Share on other sites More sharing options...
