These visors were the subject of controversy some 10 years ago, due primarily to the fact that they differed so much from the pre-/mid-/late-war Erels.
With the advent of documentary evidence, they are now considered to be original.

I call these the "M-45" Erels, as most were found unissued at the end of the war.
They share common characteristics, and differ from their earlier brethren in the following ways:

1. Instead of having Vulkanfiber visors, they are made of compressed, laquered paper ("lackierte pappschirm");
2 They lack the Erel "air cushion" sweatband;
3. The sweatbands are often (but not always) marked "Clemens Wagner 1938" (my theory is that Erel bought new old stock intended for CW);
4. They use a heavy ribbed Trikot for the body of the hats;
5. The crowns of the hats are smaller;
6. The peaks are lower;
7 The sweatbands lack the standard Erel patent markings;
8. The Erel/OKK logo is not foiled in (and is very hard to see);
9. The rayon is very thin, almost translucent
10. Most are mint and unissued (it is my opinion that they were found by Allied soldiers when they came upon an OKK outlet);
11. Many have the sweatband attachments on the side (vs the rear with a bow);
12. Some have factory-installed bullion wreaths;
13. They have no grade classification (ie, Standard/Extra/Privat).
