other info

• HCO was the Hadley Company, one of the
  
  main suppliers for the Air Ministry through-
  
  out WWII for servicemen and women. This
  
  pair features in the WWII section of Mick J
  
  Prodger's excellent, Vintage Flying Helmets,
  
  (still available) - check it out. And here it is,
  
  in the full kit. This is the Type C, single bridge
  
  sunglasses that were issued from 1943.
  
  Not sure if these saw any action as they
  
  were issued for many years after the war.
  
  Lenses are not that dark, 34% LTF and are
  
  good, 97% uv protective at 380nm, fine for
  
  any conditions, even at thirty thousand feet,
  
  spotting Jerry.
