As stated, the AN6530 were used both by the AAF and USN/USMC. Contracts on the box would designate service branch of supply. You will see the two piece cushions and also the full face cushion. Are the rubber cushions original or replacements? There are companies making them. Either style will work with an A-ll series helmet.   The full black rubber goggles used by the Air Corps are marked B8 and as stated have the chamois liner for the face flange. I have seen some of the general issue dust and wind goggles used with flight helmets but its not real common. Navy versions of the dust and wind goggle have USN in a circle on one side of the face flange and the date in a circle on the other side. The Army style have US and date. Navy contracts are ususall prefixed with NX or NXxs etc.    B8 goggles with Brit flying helmet. Common to see in some later war Fighter group ETo units
