The attractive - scarcely encountered and still very nicely preserved! - N.S.D.A.P.-membership-lapel-pin (ie. 'N.S.D.A.P.-Parteiabzeichen') - which has been just moderately used ie. worn - has a very nicely preserved age-patina and has most certainly never been cleaned nor polished: it is showing just minimal wear and is totally void of any (enamel)damage (as can be seen on the pictures): just some regular wear ie. minimal scratches is/are noticable. The party-badge shows the superimposed makers'-designation: 'RzM' and/or: 'M1/93' and is as such an example that was produced by the (scarcely seen!) maker named: 'Gotllieb Friedrich Keck & Sohn' as was based in the town of Pforzheim. It shows, moreover, a somewhat tarnished- (ie. minimally stained) finish as can be seen from the pictures. This example - which has a somewhat darker-red-coloured enamelled area - comes mounted onto its regular-styled pin- ie. pin/catch-set-up which is naturally still fully functional and/or present (as can be seen on the pictures). I deem this an attractive, 'N.S.D.A.P.'-membership-pin ie. party-badge (by an unusally found maker!) that is most certainly priced according to its obvious scarcity and/or desirability!
