Reichsbahn Shoulder-Boards

I just acquired a small lot of cloth 'Deutscher Reichsbahn' insignia. Set Shoulder-boards of a 'Beamte der Besoldungsgruppe 17a & 17' (sew-in type), for 'Bahnwärter'. These boards (which are still tied together) were instituted in June 1936, and were worn on the dark-blue Reichsbahn uniforms depending on the pay-group in which they were placed. These insignia originated from an old clothing depot and are 100% period and original!
