WH (Luftwaffe) machine-embroidered, trade- ie. special-career ie. proficiency patch (ie. 'Laufbahn- o. Tätigkeitsabzeichen') as was specificallly intended for usage by: 'Schirrmeister/Geräteverwalter (K)'

I recently found three - fully indentical - examples of a WH (Luftwaffe) machine-embroidered, so-called: trade- ie. special-career-/proficieny patch (ie. 'Laufbahn- o. Tätigkeitsabzeichen') as was specifically intended for: 'Schirrmeister/Geräteverwalter (K)' (or: airforce-staff-members ie. equipment-administration staff-members) and that come all three in an overall very nice- (ie. simply never used- nor mounted- ie. 'virtually mint- ie. unissued'-), condition. The patches are neatly machine-embroidered in greyish-white-coloured linnen on a bluish-grey coloured- and/or woolen-based background. The patches - which are void of any 'backing' as more often - simply show no age nor wear. My asking-price is naturally intended for a single specimen. Simply a nice occasuion to acquire a WH 'Luftwaffe'-related trade- and/or special-career patch for a justified price!
