Neat, DLV- (ie. 'Deutscher Luftsport Verband') related collar-tab 'cypher'-pair (ie. 'Kragenspiegel-Auflagensatz für die Kragenspiegel des DLV') being an aluminium-based- and fully matching pair

I recently uncovered a small stack comprising of 14 (fully identical and matching!) pairs of the early-period (I deem around 1934) DLV- (ie. 'Deutscher Luftsport Verband') related collar-tab 'cyphers' (ie. 'Kragenspiegel-Auflagensatz für die Kragenspiegel des DLV') being all aluminium-based- and/or fully matching pairs that come in an overall very nice- (ie. simply never worn- nor collar-tab-attached- ie. still 'virtually mint- ie. unissued'-), condition. The 'cyphers' are all totally void of a makers-designation and depict a 'winged propellor' and still retain all their silver-toned finish and come all mounted onto their (never bent!) copper-based prongs in place. My asking-price is naturally intended for a matching pair comprising of two 'cyphers'. Simply a neat occasion to acquire a (not that often seen!) 'Kragenspiegel-Auflagensatz für die Kragenspiegel des DLV' for a competitive price!
