Original decals are flush.  Look closely at both decals and a barely noticeable clear border/flange can be seen.  This is common among reproduction decals.  The helmet has been re ~ painted from its original color.  The black paint is not original to the helmet.  Again, the leather liner and chin straps are awesome. I wonder if it's from a movie costume department.  May have been used in some film or television prodoction decades ago.   Below are some pictures of an un ~ adulterated helmet I own that's got an SE66 stamp.  The batch number indicates this was a polizei helmet.  Hope these pictures are useful as a rough reference.     Here's another helmet I "restored" sonetime 1992 ~ 1993. The helmet cover is made from the remnants of an original Heer zeltbahn, the paint is black outdoor grill paint, and the liner is real sheepskin, made by George Birringer.  The liner suspension ring has a 1940 date.  

I personally can’t make out the heat stamp, but I took the net off and I’ll post some better photos I messed around with the settings for the heat stamp photo to try and make it a little clearer. Let me know if it’s not good enough.

Personally I can’t decide one way or the other without pictures of the decals. These pictures are way too blurry to make out any helpful details. Picture of makers stamp and good pictures of decals. Certain makers used certain decals so the pictures requested will help with that connection. 

Thanks very much 

That's good.  Prussian Wappen and cockades and the lower priced ones compared to the other states.  

Agree with Marshall 100%   Original SS helmets with double or even single decals will be in tens of thousands of dollars...   Try to find the heat stamp and makers marks and that will reveal more about the maker of the helmet as well as the markings on the aluminum liner band..   An Original SS helmet is The Crown Jewel for many who collect TR or even SS related items, and so many dubious helmets have been made over the years and the unknowing ends up spending thousands of dollars on fake junk...   Leigh 

Original DD SS helmets are worth $$$$$.

This is an interesting item.   I think these kanji are "直明" and "柳川".   I'm not a sword professional so I don't know what they mean, but they look like names.   If they were names, the former would usually be "Na-o-a-ki" or "Ta-da-a-ki", and the latter "Ya-na-ga-wa".

Could it be an 1841 Mississippi - measurements seem to be similar?

Dispatch Riders from a Flak unit HQ,I think Russia, this despite the word FRANCE we see on rail car, this perhaps being a commandeered one for German use,

RPB8   1. Rheinisches Pionier-Bataillon Nr. 8, Prussian Helmet Plate and Cockades  then.

Helmet's genuine, decals and fisherman's netting cover are fake. The liner's in awesome condition, and the leather looks like it's original.
