The History of the LFC Model

The LFC model was one of Helly Hansens military masks and was issued to the Navy. On most LFC masks is marked with "Sjøforsvaret" which means "Navy". The LFC is one of the more advanced Helly Hansen military masks, compared to the IMA and IMB which does not have a voice diaphragm. The mask was used by the navy for an unknown period until it was replaced by the NM16 (Swedish M-51).

Helly Hansen - Model LFC

The mask consisted of a big open visor which streched down the right side of the mask. The LFCs oral nasal cup was made up of green PVC as the mask itself and was transparent around the edge. The mask was equipped with voice diaphragm, which could be unscrewed. The exhale valve had the same shape as used on the IMA, IMB, and LF-62. The LFC mask used a thin 40mm filter which had the exact same color as the mask itself. The designation is not known.
