Schinkel Iron Cross 1st Class 1939 on Screwback. Type Wilhelm Deumer, Non-Magnetic.

Iron based and in a very good, slightly worn condition. The core with practically all of the black paint. The ribbing in matt silver, the flanges burnished and all with some patina.
Not marked but a known variation that has been attributed to the company of Wilhelm Deumer, Lüdenscheid. On large „clamshell“ type screw. Three piece construction and magnetic.
Very early, so-called „Schinkel“ variant. This type is corresponds in shape to the original variant of the Iron Cross, whose design stems from the Prussian architect Karl Friedrich Schinkel. From mid-1940, the Iron Cross was redesigned, this time more massive. The Schinkel variant is easily recognizable by its much narrower cross arms, compared to the later, more common variant.
Rare variant, in very good condition. !
