Special Forces Helmet.

Cannot find much information on these except that the ones i have seen previously have always been described as ''special forces'' even down to the description having the word ''Hereford'' used. I cannot be 100% sure as i found this amongst items being used on a mannequin representing a member of the SAS. I do know that the very useful internet site, GOSTAK.ORG.UK, on composite helmets have an exact example described as ''special forces'' possibly manufactured by RBR. Anyway the helmet is in nice condition with full liner and chinstrap system, one rear sweatband clip has broken.
