Iron cross 1st class by Wilhelm Deumer, Lüdenscheid. Three piece construction with magnetic, iron core and soldered on setup. Unmarked, typical early Deumer core and frame. So called "Schinkelform" with glossy black core type. Excellent condition with nearly 100% of the glossy black core paint still present. Comes in a nice early period case with black inlet that is also in a very good to excellent condition.
Schinkel crosses have become very rare these days. This is a fantastic example of these crosses. It's a very early Schinkel cross as the well known flaws on the rim are completely absent.
Top textbook cross, top set!
