ISO USED casting mold for 5lb lead Hammer?

[y'sguy]

I know that these are available new and even as a hammer-making kit. However, I am looking for just the mold if anyone has something they care to sell. I can come up with the rest of the stuff to make the lead hammer, I just don't want to spend the money on an entire kit.
This will be used for Knock -off wheels.

Let me know if you have anything. Thanks.

looks like this.
