I am talking about the same thing is you. The latch setup is a bit
different, I noticed, and I did not disassemble it.
Yes you can cast lead in plaster. You will need a two piece mold to do this
right since the front is formed as a cone-shaped indention as well as the
back, whose circle pattern has a flat across one end giving is a slight D
shape. It's a little more complex than just a washer.
