AN-6530 Goggles
Above:  Vintage photos will show the wear of flight goggles with "split pads" along side the single piece cushion which was designed to replace them for the AN-6530. It is our opinion that they were originally manufactured for the B-7 type goggle and production schedules or supply shortages necessitated their use at times by both manufacturers.

Below:  Two styles, as illustrated here, can be found. Only one has the molded part number.
Above:  TSGT Jack Pittman, USMC, in the cockpit of his Corsair, wears A.O. goggles with "split pads" (no part number), clear lenses and a white strap.

Below:  A TBF crew from VT-5 aboard U.S.S. Yorktown in the summer of 1943 displays a mixed bag of goggles. The radioman (at left) sports single cushion C.F.S. AN-6530s, the pilot (center) has kept his MK-II goggles and the gunner (right) uses a pair of "split pad" A.O.s. 
Above and below:  It is typical to find the American Optical production "split pad" goggles in a distinctive box. In addition to it being covered in white paper (as opposed to brown cardboard with just a white paper label) the box is also smaller, only 1 3/4" tall and 3" wide. The box for the C.F.S. "split pad" goggles is no different than that for their one piece cushion goggles.
Below:  Another VT-5 crew, that of LT (jg) Arthur A. Curtis. His gunner, "Cosby" on the left, and radioman, "Ted" on the right, both wear A/O "split pad" goggles.
Above right:  Vintage photos of the "split pad" with a molded part number, in Navy use, have proved to be rather elusive, but can be found. This production variant has the retaining bands mounted inside the cushion eye openings.

Below:  An example of the pads seen above, at right, in dark gray rubber with molded part numbers and retaining bands mounted inside the cushion eye openings, fitted to Charles Fischer Spring frames with riveted upper vents.
Below:  Another example, this time a pair of A/O goggles with interior retaining bands. The goggle headband and first pattern AN-6540 summer flight helmet are both marked as belonging to "MANZO", although no further identification of this flier has yet been uncovered.

We cannot make a definitive statement, but circumstantial evidence leads us toward the conclusion that the "spit pads", when used with American Optical manufactured AN-6530 goggles, were of the type shown below, with no molded part number and interior retaining bands.
Above and below left:  Major Boyington again, with a different pair of AO split cushion goggles.
Below:  From the collection of "GOZ" comes this interesting variation. These are Charles Fischer Spring "split pads" of the type that would have the molded part number and the retaining band mounted outside the cushion eye openings. This recent acquisition, attributed to "R. F. Chadwell", has had chamois covers cemented to the front and rear of each cushion and feature plastic lenses.
