Actually info research has gone on quite well. An old acquaintance in the UKput me in touch with a party in Israel who actually went and talked to the inventor/makers sister, who is still alive. The old girl has a mind like a bear trap and was able to shed a lot of light on the scope and the inventor himself. She knew a lot of detail on the scope, manufacture and its use in the Israeli military. The inventor was the type of guy they should make movies about and his life story makes James Bond 007 look like a Sunday school teacher (international intrigue and all documented). A MAJOR international company we all know figures heavily in the story. All to come in a short treatise that I am working on. So much to do and so little time. Don't know how people die of boredom when they retire. I need a job to look forward to two days a week off. :-)##
