Yet another relic ss helmet ? After the last 4 or 5 ones you have posted maybe you should be looking and picking up some reference books first.
I assume you own all these items and not sure if you've been collecting on your own (like I did when I started out) or what, but this is (or can be depending on what you collect) an expensive hobby.
As noted above, to truly learn your stuff, one needs to slow down and study. Buy GOOD reference books and study the posts on the forum. Listen and learn from the guys here.
Otherwise you wind up with a collection that is not what you expected and out a lot of money. In this hobby, unless you get something out of the proverbial attic, you get what you pay for.
But I will say, you've been taking the news on some of your items fairly well so far.
