Redherring Posted October 3, 2014 Share Posted October 3, 2014 Hello all. This has graced my office for some years and many people have puzzled over its usefulness. I have had to admit I have no idea of its provenance. Can you enlighten me? Robert Quote Link to comment Share on other sites More sharing options...
Adrian Barrell Posted October 3, 2014 Share Posted October 3, 2014 It's a sighting telescope from a Director for anti aircraft fire. http://en.wikipedia.org/wiki/Director_(military)#mediaviewer/File:M7_director.jpg British machines were known as Predictors.

Adrian Barrell Posted October 4, 2014 Share Posted October 4, 2014 There are several variations and are quite common over here. On ebay they are always a tank sight and worth a fortune..... Quote Link to comment Share on other sites More sharing options...
