MikB Posted 16 November , 2013 Share Posted 16 November , 2013 I've asked this question from time to time in the hope that someone might have come across a source: When civilian 'optical munitions' were accepted for military service in the emergency of 1914-15, they were marked up with grades relating to quality and design. Grading of binoculars is documented in Fred Watson's booklet (no.317 in the Shire Albums series, ISBN 0-7478-0292-0), but I've never found the corresponding grade definitions for telescopes. I have a Negretti & Zambra 'Laird' big-game telescope bearing the Broad Arrow. This scope is a dead-posh, top-of-the-range job with a 2 3/8" achromatic triplet objective with astonishingly low reflective losses between elements, a 30-35-40x pancratic slide and nickel-silver drawtubes offering a weight saving of 14 ounces compared to the same model in brass. It sold for £14-15s-0d in the 1921 catalogue. It must have been one of the best hand telescopes available anywhere in the world at the time, but it got marked up as a 'Special, Grade 2'. I can speculate about its larger size than the GS telescope, the fact that it didn't fit the standard tripod, or its difficult-to-disguise blingy material, but if anyone knows how the 'Specials' Grades were defined for telescopes, I'd be grateful to know. The picture shows it with its smaller brother, the 'MacLeod' - which has no military markings. Regards, MikB Link to comment Share on other sites More sharing options...
