'Infanterie-Sturmabzeichen in Silber' being a non-maker-marked, 'hollow-back'- and/or zinc- (ie. 'Feinzink'-) based specimen of the so-called: 'egg-head'-pattern (as presumably produced by: 'Gustav Brehmer')

This is an attractive - and actually quite scarcely encountered! - example of a: 'Infanterie-Sturmabzeichen in Silber' (or: silver-class infantry assault badge ie. IAB) being a (typical) non-maker-marked-, 'hollow-back'- and/or typical zinc- (ie. 'Feinzink'-) based specimen of the so-called: 'egg-head'-pattern as was produced by a to date unidentified maker (presumably by the maker: 'Gustav Brehmer') and that comes in an overall nice- (and I deem just moderately used- and/or clearly worn-), condition. The war-badge on offer here concerns a (I deem somewhat later-war-period) zinc- ie. 'Feinzink'-based specimen that has maintained an attractive (typical zinc-like) greyish-toned appearance, still showing pronounced detail as to be expected. The badge has never been cleaned nor polished (and is still also a tiny bit tarnished as can be seen on the pictures). As stated above, does it deal with a so-called: 'egg-head'-pattern that naturally shows all the details as to be expected for a badge by this particular maker. Simply a nice - and honest! - silver-class, so-called: 'egg-head'-pattern IAB that comes in an overall nice and just moderately used- ie. worn condition and that is (I deem) accordingly priced!
