This is my next Belgian helmet, Belgium used a lot of different helmet models, wich makes them very interesting for collectors like myself. This example has been used by the Belgian army.
This type of helmet has been produced and used since 1951 up to the nineties.
It looks like the US M1 but is mainly manufactured in Belgium by Belgian companies. I don't know who made the shell of my helmet but the liner has been made by the company NV Menten SA: http://www.levior.com/site/frames.htm from Tongeren. Levoir is one of their brand names.
Almost every Belgian helmet has a flag sticker at the left side.
In the liner there is also a stamp ABL 1979, ABL = Armee Belge, Belgisch Leger.
