Collar-tab device (ie. 'Auflage für Kragenspiegel der SA/SS-Fliegerstürme') being a bright golden-toned and/or 'Buntmetall'-based specimen that shows a 'P&C'-makers-designation on its back

This is a neat - and actually not that easily found! - so-called: collar-tab device (ie. 'Auflage für Kragenspiegel der SA/SS-Fliegerstürme') being a bright golden-toned and/or typical 'Buntmetall'-based specimen that shows a clearly present: 'P&C'-makers'-designation (and/or: 'Ges.Gesch.'-patent-pending-marking) on its back and that comes in an overall very nice- (ie. I deem simply never used nor tab-attached- ie. still 'virtually mint- ie. unissued', condition. The detailed piece retains both its (I deem never bent and of course still functional) prongs in place. Simply a very nice - and unusually found! - insignia-piece that was intended for usage by the: 'SA/SS-Fliegerstürme'!
