From the first sight this EK 1870 looks fine, metal looks like silver, diameter is 42mm, everything is unmagnetic (expect the screw)
Borders of frame are quite strange, black paint covers the frame and looks like it was hand-made.
MUNCHEN 9 mark... It is quite werid to mark the cross with uncompleted street name (Deshler & Son foundry was placed on Munchen 9 Wirthstrasse 9).
Tell me what do you think about it. And also what odd You have seen on this cross.
