|This early version of APH-6 serie utilized the same typology of APH-5 visor shield as well as the earphone fixation system still without the large plastic ring under the bolt head.This very early version of APH-6 series (still with no letter designation) was introduced during the early 60′. Its shell is constructed of a polyester impregnated fiberglass cloth laminate and the visor shield/locking mechanism was the same as the APH-5 later version as well as the internal liners and earphone fixation system. The APH-6 shell introduce the new and unique „Butterfly“ retention and release assembly used to secure the oxygen mask, APH-6 helmets from this era look very much like the APH-5. Its earphones are attached with a single screw through the helmet shell, it has large padded earpads and fitting pads, all covered in tan-coloured leather and a single visor,The styrene energy absorbing liner consists of three parts split longitudinally.|
The only differences seem to be that the APH-6 has a thin rubber edge beading instead of the APH-5 neoprene edgeroll, and then of course the APH-6 has its special racheted oxygen mask receivers that take the so-called butterfly bayonets,this helmet,Helmet is in very good normal flight use condition for its age, helmet and mask with all plugs and connections, only the Y cable for the mask-helmet connection is missing!
