emile... Yes the shell is defiantly an Austrian made m1 clone...as made for the Dutch... I think the Austrians also supplied quite a few country's with similar shells Netherlands, Denmark, Norway.. too name a few...but i also think there is still the probability that this Turkish liner was actually intended only as a parade type as it looks identical to the parade one's worn by the guards in the photos.. .. it seems to fit the shell very well though!!!
BG ...... Think you may need some serious ear defenders!! As even background noise seems amplified whilst wearing these helmets!!!!! Not to mention the funny looks you might receive at the range!!!!
