This badge has a typical sheet-metal hinge, found on so many other Brehmer badges. Though not extravagant they did their jobs. Note the hand finishing gives the edges a slight bevel.
The feet of the Brehmer are quite reminiscent of numbered Panzer Assault Badges by Brehmer; they are large and highly detailed with speckles covering them. The arrow- head central talon on the right side has the same notch in it as the Tombak version.
A critical feature is the split 7th rivet. Count from the right along the row of rivets at the base and the 7th one always has a bit of flashing on the bottom, almost splitting the bead. Check the Tombak version and you will find it is a die characteristic. Also note the three curious rivets between the breech and gears. On any other badge they would all be rivets or circles, but Brehmer gives us a mix. We again see the break in the bar connecting the two wheels. All of these details were part of the die and should ALWAYS be present.
