Nelson Lapidary trim saw rock cutter 6" with motor

Hello, this Nelson brand made in Portland Or lapidary trim saw uses a 6" blade that I think is a diamond type. It is in nice shape and comes with a vintage G.E. 1/4 HP motor that works. I did find that the metal part thats connected to the clamp that sits in the track needs a new set screw intalled. I accept money orders.
