HGU-2A/P OH-FMM ( FM-51 ) FOUGA MAGISTER
This HGU-2A/P dual visor "ramshorn" was used during Sakari Sivula's era with OH-FMM ( ex. FM-51 ). The helmet is size X-large. It has all pads inside. Earphones have spring arms. There is a ILMAVOIMAT ( AIR FORCE ) sticker on rear with a manufacturer's label ( Sierra ). The oxygen mask is a 77/78/79 dated MS22001 with a mic, which looks like a RAF/RCAF used one. This set came with a throat mike. It was used by Sakari Sivula with Fouga CM 170, the first owner of the OH-FMM, it is also a very good example of pure Finnish Air Force Fouga pilots used HGU-2A/P and MS22001 oxygen mask. Finn Fouga pilots used also USAF MBU-5/Ps according to Air Force photos. Nice clean helmet with known history! I've added Fighter Squadron 31 sticker later.
And what makes this helmet so splendid...is that it has all pads inside. Those pads are usually missing or deterioring.
"ILMAVOIMAT" aka "AIR FORCE" sticker on rear.
MS22001 oxygen mask has "T"-style bayonets. Mic looks like RAF/RCAF used one with ON & OFF markings. Soft part of the oxygen mask is marked SILICONE and it is dated 77/78/79. USN used also MS22001 masks but without a mic like this one. USAF used also MS22001 masks specified as MBU-3/P. Finnish Fouga pilots used earlier RAF Mk.1A helmets with H-type RAF masks so that speaks for the reason why MS22001 is fixed with RAF style mics.
Throat mike is fixed for the single "T"-style bayonet with an adapter.
Here is the throat mike and mic's plug.
