And with respect to digital magnification -- Yes you do have to look that deeply or your not looking hard enough to prove or disprove your case. THis is what was done with the Heimwehr Danzig helmet here on the forum, one of the methods used to determine authenticity.
400x Digital magnification looks "into" the decal, so you can see what the age of the decal is along with the exact layering and construction. I have examined about 100 real SS decals in this manner and quite a few fakes, this way and there are clear differences.
If your decal exhibits qualities of these fakes found below then the answer is clear. Real SS decals including the variants are not like this construction and fakes seem to always miss one key component.
Below are examples of several fake EF SS decal, fake Italian SS decal, fake roundbottom SS ET decal, and a fake unapplied ET using modern digital printing charachteristics.
Schwerpunkt probably lives near you, he is using 200x digital magnification. He could probably meet you and show you what it is about and shoot your decals.
Also, this exposes repetitive tool marking and modern paint as that reflects whereas period paint being truly 65-70 years old does not. It also shows fine age checking that a loupe or the human eye misses.
Fake decals can run from ADM (Advanced Digital Magnification) but they cannot hide.
Very interesting thread, and a nice helmet if its genuine Looks like collecting rare helmets has become an almost very precise and exact science
If I got one dirt cheap I'd throw all technology I could at them. Starting with ADM.
Frw , do you have any "regular" helmets in your collection ? Like a plain SD SS M35/M40 or M42 or Heers LW's etc ?
If so would love to see them.
