@KoiwiGal - You don't have to buy a commercial mold to make those lead figures. There are instructions on how to make the molds online. I believe you can make them out of silicone.
You just need your own lead melting pot and to make sure that you have all the safety equipment. This is especially true if you are making your own molds as they will not be as safe as commercial molds. Be extremely careful.
That said, I remember seeing a set from the 60's that was supposed to be a toy soldier maker for kids. It was supposed to be for pre-teens, but it included real lead smelting equipment!
If the children of the 60's can do it, you can too, but just be careful. Molten lead is not a plaything and it can seriously harm you.
