[QUOTE=Miro;1320704] I know your EK2 twin. It was my reference cross when I studied this Prinzen type.
I'm glad I was able to help.
I found my Prinzen on ebay many years ago. There were
hardly any bidders because the seller was unsure of it's
originality because it was not the correct size. I don't
remember the exact price but I know it was under $50.
