These unmarked Iron Crosses in 2nd Class are very difficult for me to identify unless there are some clearly identifiable characteristics, i.e. Souval. The closest "guess" I am willing to make is an unmarked "55", J.E. Hammer & S?hne of Geringswalde, based soely on a visual comparison of the following features, the last "9" in "1939" appears lower than the second "9", the beading, almost flattened on the high points, and the inconsistent cross-hatching on he inner corners. Finally, the shape of the swastika, and finish of the core compares quite similarly to other "55's" on file in our Databank. This is just my "guess", gentlemen. . .
