Bright-silverish-toned- (and I deem tin-based) so-called: 'photo-album-device' being a non-maker-marked example depicting a German steel-helmet

This is an attractive - and most certainly unusually seen! - (bright) silverish-coloured- (and I deem typical tin-based) so-called: 'photo-album-device' depicting a larger-sized WWII-period German steel-helmet (with decal!) that comes in an overall nice- (and I deem used- and/or once album-attached-), example. The larger-sized device - measuring approximately 5 x 2,8 cms. - was as such (I deem) intended for usage on a photo-album or scrap-book or alike. The detailed badge comes mounted onto its period prongs in place (for album-attachment) and has I deem never been cleaned nor polished: it shows some minimal staining (as can be seen on the pictures) but is still very detailed and/or pronounced. The badge retains most of its (somewhat 'frosted' ie. tarnished) silver-coloured finish. Simply an attractive - and actually unusually found! – WW!I-period related so-called: 'photo-album-device'!
