Interesting, veteran-related 'N.S.R.K.B.'- (ie. 'Nationalsocialistischer Reichskriegerbund'-) bright-golden-toned: 'N.S.R.K.B.'-visor-cap eagle-device

This is an attractive - and most certainly not that easily found! - veteran-related 'N.S.R.K.B.'- (ie. 'Nationalsocialistischer Reichskriegerbund'-) ie. WWI-veteran-association, naval- (ie. 'Reichsmarine'-) related bright-golden-toned: 'N.S.R.K.B.'-visor-cap eagle-device that comes in an overall nicely preserved- (I deem used- and/or cap-attached-), condition. The eagle is a bright-golden-toned (ie. 'feuervergoldetes') example that has an approximate 'wingspan' of only 6,5 cms.: it regrettably misses its prongs but does show a fully preserved black-coloured (ie. neatly painted- ie. sprayed) iron-cross-symbol attached (as can be seen on the pictures). The piece is void of a makers'-designation but does show a stamped : 'Ges.Gesch.'-patent-pending-designation on its back (as can be noticed on the pictures). This interesting eagle-device was recently uncovered at a German private-household and was stored as such for decades: it was never before part of a collection. Simply an interesting - and most certainly quite scarcely found! - naval, 'N.S.R.K.B.'-related visorcap eagle-device that is I deem priced according to its missing prongs!
