Superb, commemorative plaque (ie. 'Erinnerungs- o. nichttragbare Auszeichnungsplakette') showing an N.S.K.K.-eagle-device and text: 'Für Sportliche Leistungen' and that comes stored in its period etui

This is a very attractive - and with certainty not that often- ie. most certainly scarcely encountered! - silver-toned- (and I deem silver-toned, 'Buntmetall'-based) so-called: N.S.K.K.-related commemorative-plaque (ie. 'Erinnerungs- o. nichttragbare Auszeichnungsplakette') showing a detailed and pronounced N.S.K.K.-eagle-device and text: 'Für Sportliche Leistungen' and that comes stored in its period (and nicely maker-marked!) etui as issued and stored for decades and that comes in an overall wonderful and truly nicely preserved, condition. The neat - medium-sized- and/or regular-weight-piece (having an approximate diameter of 5,0 cms.) has truly pronounced detail and was never cleaned nor polished: it has maintained a neat typical, silver-toned age-patina (but also shows some minimal tarnish as can be seen on the pictures). The piece shows a silver-content-mark (that reads: '990'). The back of the medal shows the engraved text: '3-Tage Harzfahrt 1934' (as can be seen on the pictures). The piece came stored in its period bright-red-coloured- and/or luxuriously-styled etui ie. box as issued and stored for decades. This etui comes in an equally nicely preserved condition and shows in its top-lid a detailed so-called: N.S.K.K.-eagle-device and makers-designation that reads: 'Robert Neff -Berlin - Bülowstr. 101'. These attractive - semi-official - N.S.K.K.-presentation-pieces were presumably used as some sort of awards as (presumably) handed-out at a specific N.S.K.K.-related sports'-tour held in 1934. Simply a very attractive and with certainty unusually encountered table-medal ie. 'Erinnerungs- o. nichttragbare Auszeichnungsplakette' that might merit some further investigative work!
