Belgian L.702

The S.B.A. L.702 was the most abundantly produced Belgian gas mask before and during World War II.  They were made out of high quality rubber with non-replaceable glass eyepieces.  These were for civilian use.  The top two examples are equipped with a 25mm filter, while the bottom example was fitted with a 40mm filter for export to Sweden and designated "Typ 14".  All were made by Société Belge de l'Azote between 1938 and 1940.

Société Belge de l'Azote = "Belgian Society of Nitrogen"
