They make kits for the hand casting, tiny soldiers and then painting them brigade.
The metal ingots they sell for home casting are low melting point products and tend to wear or scratch easily, however it is very satisfying to make your own.
Why they adopted the name of a pro-Nazi Prussian prince remains a mystery to me.PA2047: Model Metal (54% Lead / 11% Tin / 35% Bismuth). It contains bismuth which reduces the melting temperature and shrinkage. While most alloys shrink while solidyfing, Model metal does not. Melts at 138°C (280°F). Cast at 300-320°C.
PA2057: Standard Metal (65% Lead / 2% Antimony / 33% Tin). Melts at 210°C (410°F). Cast at 320-340°C.
PA2060: 5 Star Metal (94.5% Tin / 3% Zinc / 2.5% Antimony) is the safest metal as it is lead free. Melts at 230° C (446° F). Cast at 320-340°C.
