FULL BOX. containing 190 slides showing Ships of the U.S. Navy........ WW2 each slide is marked U.S. ARMY AIR FORCES....... with name or type of ship, aircraft carrier or submarine featured on the slide..... there must have been another box to make the set of 375 as described on the box lid, this box is full and holds 190... I know these sets also exist for planes and armoured vehicles and were used to train Pilots in recognition lectures......... very unusual to find a full box in perfect condition........
