HGU-2A/P. This particular helmet is still a mystery, as no facts about its

service use are known so far. We know only of one picture showing a

Swiss AF pilot holding such a helmet, but no further information exists. The

rivets along the visor edge are evidence of previous shell use with a "ramshorn" visor cover.

As a Swiss AF standard, a British MK-1 visor assembly is installed.

The three holes on top of the helmet crown are characteristic for the early HGU-2 models.

The spring loaded headset brackets.

The bailout bottle connector identifies this MS 22001 as used on Vampires.
