79) A very nice WW2 Royal Navy OOW single draw telescope. In excellent order with lovely clear optics and just one very slight edge dent to the outside which looks worse in the photos than really is and does not affect it or its use. (see photos). The black rough textured grip is excellent with just slight wear. The sun screen is a little scratched but pulls out well. It looks to have been black originally? The single draw pulls out with ease and works nicely. The eye piece is good but. Made by Ross. London. it has the NPL (National Physical Laboratory) inspection mark dated 1944. when closed it measures 13 inches in length.
