GUENEAU 316 HELO
Despite being considered too heavy for helo operations quite from the beginning of its introduction, the Gueneau 316 was in some cases used on Sud Aviation Alouette II/ III helicopters,
instead of the standard SPH-4. This might have been a question of "personal choice" of certain pilots.
This specimen was worn by a former Locarno-Magadino AFB commander during many air rescue and fire fighting missions.
