'Regimentstag Füs. Regt. 73 Hannover' Tinnie (Veranstaltungsabzeichen). Originally dated 1929, but over stamped with 1934 date, probably the gathering was held again and the same tinnie was distributed.  The tinnie is very lightweight, stamped from a thin metal sheet. The tinnie comes on its original pin/catch construction. Maker marked by 'Lehmann & Wundenberg'. Nice example in good condition!
