Wartime manufactured German Hungarian military steel helmet used during WW2 by the Hungarians fighting along with its allied German army. It has the same shape of the german M35 but a different liner and different rivets position. A hook is present on the rear to hold it when marching. This example shows a blue-grey paint, some say this colour it might indicate it belonged to aviation troops, but I rather think it was for civil defense. Shell size should be 66, markings are no longer visible.
