Potentially all Original German WW2 Blau Division Helmet M35. There are differences of opinion on whether the Decals were applied during the war. It looks to me like there are 2 failed attempts made to apply the decal properly.
The two previous decals were removed but they kept the third. Everything is Original down to the decals the only question is when the decals were applied. In the liner the words VIVA FRANCO.
