'SA Gruppe Donau Gruppen Wettkämpfe' 1939 Tinnie (Veranstaltungsabzeichen). The off-white coloured plastic type tinnie has a pin-back device attached to its reverse. The tinnie is nicely maker marked by the company of 'Richard Sieper & Söhne' from Lüdenscheid. Due to the white colour the tinnie is very difficult to photograph. Nice original tinnie in very good condition!
