Armbands, any good?

[Eddie]

Listed really cheaply on an auction site, I've never bought one of these before. Some looks salty enough to be legit IMHO, but I seem to be wrong almost everytime!
Thanks!

P.S. What is the significance of a wool armband? Obviously better quality, but does that generally mean Party Member armband rather than simply something that someone wore at a parade, or just simply better materials?

#1 appears to be good, #2 & #4 possible but unable to definitley say they are 3rd Reich, especially #2. #3 is a definite reproduction of an early NSDAP official armband. Wool armbands were worn on a tunic where cotton were worn on a brownshirt.
