I bought this lovely old Swift Sea Hawk, model 753A, from the same collection dispersal as the Zeiss 7x40 I posted today. It is mint, never used, boxed with all accessories and paperwork. I have been selling of some of my collection as I need space, but I just could not bring myself to pass these by. Very much the same military spec as my Bushnell US Navy navigator 7x50, and the Fuji AR, but without reticle, like those it was made by Kamakura Koki Co. Ltd. JB 133. It gives a very good sharp image, but to my eye my Bushnell seems marginally brighter, and feels a little lighter. FOV is [email protected], nitrogen filled, waterproof. Not sure of the weight, but it does feel heavy. Nice binocular, but the best Swift IF 7x50 I have seen is the superb Storm King MK11, it is bigger and heavier, but optically superior to this, even though it's older.
