Vintage KERR Centrifico Casting Machine for Dental or Jewelry Castings

Description

Vintage KERR Centrifico Casting Machine for Dental or Jewelry Castings.
No.058674.  Won this item from an estate auction and really don't know much about it,
How it works? or anything. but it appears to be in really good condition and if you turn the top
the mechanism spins it around to where it wants it. also the other arm can swing around also.
Seems to work smoothly and effortlessly. Please check pics! I will detach the top arms for shipping.
