Robert, I have seen a couple like yours and others, can't recall just what the others depicted. A tank is a foggy possibility. Seems there was a series of pins. Usually see them grouped with tinnies. Think one stated fit for service or something like that. I also feel yours is a two part piece. --dj--Joe Went looking - found a couple - one was plastic with the folded metal plate stating Jnfanterie. Depicted an eagle above and a helm., rifle, bayonet and oak leaves below. The other - in metal, depiction was also an eagle above but below a helm. with a bayonet and different oak leaves. The folded metal plate stated Wehrfabig I think? It was rusty. One more - in metal, had the RAD or FAD emblem (no swaz.), depicted within a shield shape below the plate stating Reserve hat rue. One other - in metal different eagle above. Helm. and bayonet in circle with different leaves below. Plate/bar plaque whatever is correct stated Jnfanterie. I would bet Wood knows much more about these than I do.
