Membership-lapel-pin: 'Nationalsozialistischer Kriegsopferversorsung' (ie. 'N.S.K.O.V.') being a non-maker-marked example

The neat TR-period lapel-pin (ie. Mitgliedsabzeichen des Nationalsozialistischer Kriegsopferversorsung' (ie. 'N.S.K.O.V.') is executed in golden-toned metal (ie. I deem 'Buntmetall') and is a nicely preserved example that just shows some moderate age, wear and/or staining but has no real defaults whatsoever. The lapel-pin is not maker-marked on its back but shows a clearly present: 'Ges.Gesch.'-patent-pending-designation on its back (as can be seen on the pictures). The lapel-pin - which comes mounted on its functional pin- ie. pin-catch-set-up - is also figured in the 'Heering-Hüsken Abzeichen'-catalogue wherein a similar example is given a unique reference-number (nr. 5706A). The piece on offer was - I deem - period-cleaned and does show some regular age and/or staining (as can be seen on the pictures). I deem that I have priced this still attractive 'N.S.K.O.V.'-lapel-pin, accordingly!
