Great helmets and great pics! The M15 Wurtt. is a rare beast here in N Am. I got mine years ago at the MAX show and I have owned one other which I sold. It took Tony S. years of searching to find his as well. So 3, in 30 years of collecting and now a pic of #4.
Yes Brian ,well spotted ,On page 67 and 75 in the wonderful reference book “The German Army in the First World War “ we can see a Bavarian Filz and a stahlblech helmet ,both with silver cockades but very different shades of grey :-# ..I mean blue…
