I find this interesting the video one because my father had a foundry that would make engine parts and other things out of gray iron & steel ,I worked in the core room in the 60s when I was young making a little Cores with sand like at the beginning of this video. my son has a 37 Chevy and this is only one year difference ,it's definitely old time craftsman an old-time machinery some parts of it may be used today.
