When you think you have seen most of the Z1 parts

I've often thought I'd like my own little aluminium foundry. Certainly not to replicate this, but still...

I wonder what happened to all the aluminium foundry supplies that got orphaned after some d-bags decided there was no value in teaching kids stuff like that in American public schools. I spent an awful lot of my time between the ages of 12 and 18 pounding green sand. Good times.
