Has anyone served in the Royal Navy between the 1970's / 1990's ?? I have two binoculars which are RN issue which date from the 1970's -1990's ( my guess) - I would be very grateful if anyone can tell me anything abourt them . So far I am on a hiding to nothing and would be delighted if anyone can help me out. The two Items I pciked up on eBay over the past two years. The large of the two came in its transit case the id plate of which I have reproduced here. also a servicing tag which was in the box. The second one is much smaller unfortunately someone cut the electrical power lead away. I am told that both have internal filter systelms and heating elements which are electrically operated, so far I have not attempted to provide them with power. Are these general observation items or part of a weapons system ? The binocular is described on the information plate as being G386/1 Binocular Ser. No.40. Any help would be much appreciated seems that info on post war stuff has yet to be written !
