Got this Sun 504 with some other parts. Don't know the history but it seems all there except for the back plate. I haven't tried to test it since I don't know anything about it and don't want to short anything out since the test leads are frayed. All knobs and switches function and the dial spins by hand. The hand crank adjustment to accommodate for different distributors moves up and down but the shafts it moves on have surface rust so they don't have a complete range of movement. The motor may or may not be original - its a GE motor connected to the drive unit by a belt. The vacuum pump is there but the hoses are cracked. See the photos for more details. Any ball park figure on what its worth is appreciated. Thanks in advance.
Yup, I have that same machine, I have had it for decades.. they are tough to ship, I would get it running and see if it works...
