It is interesting how this particular black coverall has what I call "the purple curse"!
Sadly the same dye was used on a Heer tanker, that had an unpiped wrap tunic( forget the name).
I gathered about a dozen loose sets and eventually I gave tgem all away. I even tried boiling them with heavy RIT dye(Black) and left them standing for days and it made no difference! The puzzling fact is that when you look at these pieces tgey look fine, but when you take photos of the pieces, be it with natural or artificial light, the purpke- brownish hue comes out. So that makes Kurzmaul's non piped heer cut wrap PRICELESS!
Nice looking mechanic!
