a French Gueneau Type 317-1 flight helmet. This specific model was a staple of French aviation (specifically the ALAT - Aviation Légère de l'Armée de Terre or Army Light Aviation) and was commonly used by helicopter pilots from the 1970s through the Gulf War.

​Identification & History
​Model: Gueneau Type 317-1.
​Origin: France (Manufactured by L'Optique Scientifique).
​Usage: Primarily designed for helicopter crews (such as those flying the Alouette III or Gazelle).
​Features:
​Dual Visor System: It features a retractable amber/yellow visor (for high contrast in hazy conditions) and a dark/tinted visor (for sun protection).
​"Type 317-1" vs "317": The "-1" variant typically signifies the absence of a thick leather headband found on the standard 317, which was used for mounting early night vision equipment.
​Construction: A monobloc shell with six ventilation holes (the brass-colored grommets on top).
​Comms: It uses a Socapex connector (the large plug) and likely an Elno microphone.
​Condition Observations
​Pros: The dual visors appear to be intact and functional, and the interior leather padding (though worn) is present. The original "Casque S.O.S. Gueneau" sticker is a nice plus for collectors.
​Cons: There is visible surface scuffing and paint loss on the shell. More importantly, the internal wiring appears frayed or disconnected in your interior photos, which is common for surplus gear but affects the "plug-and-play" value.
​Estimated Value:

R2,800 - R3,800
