Those helmets are indeed looking as if they were made/resprayed yesterday. A resprayed helmet, added with some 15 P plastic “Airfix like” decals aren’t worth anything more than maybe 40- P.St.
I have some 50 German Helmets (aswell as some 80 from other countries) and even when they look almost “like new”. they have a 60 year patina in/on the paint and decals.
Today, I guess 95% of the German helmets offered for sale WITH decals are fake!
Going to post some of my collection, and you can clearly see the difference. BW Roger (Helmet collector since 1973)
