At the end of the 50's the APH series helmets introduced a new generation of flight helmets characterized by the external visor covered with a protective shield. Improvement of the communication system, internal liner and oxygen mask retainers was also made and in some versions the dual dark and transparent visors system was installed. These types of helmets were the US Navy and USMC standard jet aircraft headgears during the 60's and throughout the 70's. In this period the first development of a flight helmet incorporating the Visual Target Acquisition System (VTAS I) was also made. Furthermore during the late 60's, flight tests were performed to verify the suitability of a full face \"Clam Shell'' helmet designed to eliminate the oxygen mask and to give better protection during ejection.\u003c\/p\u003e\n\u003cp\u003eThis is a great Vietnam War example of the APH-6 series that we cannot identify to its specific type as the original data tag on the back is now covered by the period-applied camouflage paint. Its shell is constructed of a polyester impregnated fiberglass cloth laminate and the visor shield\/locking mechanism was the same as the APH-5’s later version as well as the internal liners and earphone fixation system. The APH-6 shell introduced the new and unique \"Butterfly\" retention and release assembly used to secure the oxygen mask.\u003c\/p\u003e\n\u003cp\u003eThe oxygen mask is marked:\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eMASK, OXYGEN, PRESSURE BREATHING\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eMS 22001-5 MEDIUM\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eSIERRA ENG.
