German Bakelite Box for "Bd.Z.(5103) der 3,7cm Pzgr.' (Bodenzünder (5103) der 3,7cm PanzerGranate). The box originally contained base fuzes used for the 3,7cm Flak and KWK/PAK armour piercing rounds (Panzer Granate). Empty brown coloured bakelite box. The box is nicely matching marked and dated 1939. The box is sized approximately 15,5 x 15,5 x 4,5 cms. Nice original example in very good condition!
