Bright-golden-toned, DLV (ie. 'Deutscher Luftfahrt-Verband') supportive lapel-pin (ie. 'Werbeabzeichen DL') being a non-maker-marked example

This is an attractive - and actually unusually found! - bright-golden-toned and (I deem tin-based) so-called: DLV (ie. 'Deutscher Luftfahrt-Verband') supportive lapel-pin (ie. 'Werbeabzeichen DL') being a non-maker-marked example that comes in an overall very nice- (albeit I deem minimally used- ie. most certainly worn- and/or used-), condition. The oval-shaped piece - which is executed in bright-golden-toned metal (ie. 'zinc') and that is totally void of a makers'-designation - comes mounted onto its still functional (long-sized) pin-set-up (as can be seen on the pictures). A similar example is also figured in the Heering-Hüsken 'Abzeichen'-catalogue wherein it is given a unique reference-number (8815K) and an estimated value of 120 Eu(!). Simply an attractive (and I deem early- ie. even pre-war-period!) 'DLV-'Werbeabzeichen DL' that is I deem accordingly priced!
