Not to confuse the process of making toy lead soldiers with these little horse and riders. William Britain did first come up with the brilliant idea to pour molten lead into a one piece mold then pour out the excess before it set up in the core. This was the first of the hollow cast lead toys, back in 1893. These little H&R figures were made in two piece molds which was an idea from earlier on. The example of the one in Humes book was from a two piece mold and was found in Colonial Williamsburg, and is represented as being from 1750-1790. So there is a difference between a hollow lead soldier and a two piece mold lead toy, which may appear to be just another hollow toy from after 1893.
