Looking for lead soldiers, I noticed that there are some specialty miniatures that accommodate the more esoteric of tastes, including these from The History Store.
Not that there is a benefit to having Himmler and Heydrich be in lead form so that you could melt them at will, but they are small enough to crush under foot if required.
In the book North Star, they both appear–charming at times–but with their deadly claws bared as the story unfolds.
