Unusual - and actually never before seen! - 'Der Stahlhelm' - Bund der Frontsoldaten (o. Sta)'-related commemorative pin entitled: 'Heidestreife 1933 - Gau Bremen'

This is a truly unusual - and actually never before seen! - (I deem) 'Der Stahlhelm' - Bund der Frontsoldaten (o. Sta)'-related commemorative pin as executed in (typical) silver-toned metal that is showing a detailed steel-helmet and that is entitled: 'Heidestreife 1933 - Gau Bremen' and that comes in an overall nicely preserved- (ie. just moderarely used- ie. worn-), condition. The neat badge is somewhat smaller-sized (and measures approximately 5 x 2,5 cms.): it is truly worn and shows some minimally tarnished surface (as can be noticed on the pictures). The piece was most certainly to be used as a 'sew-on'-piece: it never had a catch nor pin set-up and shows two tiny holes (used to attach it onto a tunic). I could not find much reference for this commemorative-pin but did find-out that the veteran-organisation: 'Der Stahlhelm' - Bund der Frontsoldaten (o. Sta)' organised a large rally with this name that took place on the 'Lüneburger Heide' (near the town of Walsrode) in September 1933. Simply a neat - and most certainly scarcely found! - 'Der Stahlhelm' - Bund der Frontsoldaten (o. Sta)'-related commemorative pin that would merit some further investigative work!
