nazi memorabilia

I remember when I was young, my grandmother showed me a ceremonial nazi dagger that her late husband had looted / liberated from Germany when he was stationed there in late 45 / 46. It was a huge solid thing with probably a six-inch blade and an eagle clutching a swastika on the pommel.

My father hated it, and he "disposed" of it once my grandmother died. He never told me what he did with it but I strongly suspect he chucked it in the sea or some similar approach rather than selling it to a collector.
