The Kershaw Vanguard series was reportedly manufactured from 1947 through 1958 in 7X50, 10X50 and 12X50 models. It is not often encountered, and if the number of Kershaw binoculars produced during this time period is at all similar to Barr & Stroud’s, then it is estimated that not more than 10,000 Vanguards were made.According to William Reid's “'We're certainly not afraid of Zeiss' Barr & Stroud Binoculars and the Royal Navy" between 1947-1958 Barr & Stroud’s binocular production averaged about 2,500 per year, a very low number which is attributed in large part to the influx of Japanese binoculars.
Even in the unlikelihood that Kershaw’s binocular production exceeded that of Barr & Stroud and 25% of their annual production were Vanguards (again unlikely because the costly-to-make Vanguard would not have been a great seller due to price and competition from other English Porro II manufacturers such as Ross and Barr & Stroud), at the most 10,000 would have been manufactured.
