Here we have a Zinc Minesweeper badge that has had an interesting life!
Solid die-Struck in Zinc with a horizontal pin attachment.
A known Product of the firm Wilhelm Deumer of Ludenscheid
The obverse finish is very good and well preserved, There has been an attempt to de-Nazify the Swastika but it is intact and well defined still
The hinge and pin is original to the badge but at some point the assembly broke off and someone re-soldered it on upside down or backwards??
Fortunately it works quite well
