I think these might actually be Stamco brand. One of my uncles had a 
machine that used a disk that looked like this but unfortunately he 
can't remember any of the details. This was back in the mid- to 
late-70's, I think and he only had it for a short time as I recall. If 
one of us remembers anything more I'll post additional info.

Regards, Brian.
