Tank assault badge for 25 attacks-Panzerkampfabzeichen mit Einsatzzahl 25, unmarked JFS

Wehrmacht Heer or Waffen SS Tank assault badge for 25 attacks-Panzerkampfabzeichen mit Einsatzzahl 25, unmarked JFS. Zinc. Very good condition. Has one factory spoilage on the second tank's wheel.  On the back side of the badge, direct under the 2nd wheel there is a back rivet which installed the tank to the wreath.  This kind of mistakes sometimes  seen on similar badges. The pin has some very minor rust spotting, and the back side silver wash has some bulging over the surface, however the face side is very nice.
