I have two of these. Both are #60 - 1" 1000 models. One is a 1959 if I want to trust the wiring diagram that was inside the unit, the other is later with the light blue handle ends.
They both run but I have never had the chance to get them all cleaned up and start using them. I thought I had once found some grinding wheels that would work, kind of skateboard wheel looking but it's been years so I might be wrong.
I know I have a operations manual but don't recall there being a separate parts manual. I'm a bit hazy. I pushed them behind my CNC mill and kind of forgot about them I have been so busy. If I get a chance I will dig through them and see what I have for manuals and stuff.
As far as the truing cams I am kind of drawing a blank. Do you mean the setting tool like this?
I believe there is only one size. Without that you can't set up the machine, I actually bought my entire second machine for $200 just to get that tool as without it I was stuck. Always thought it was dumb to have something so important not built into the machine and so easy to lose. If I recall correctly you set the distance between that ground cast surface and the diamond with a feeler gauge with the rest of the tool clamped in the jaws and the dowel indexing it.
But again it's been a while so my memory of everything isn't what it was.
The two together with the newer one on the left, you can see the design change for the stand. Also the different color handle plastic.
The wiring diagram I found in the older one.
As I said I will see if I can dig through the accessories and see if there is anything useful information wise I might have written down.
EDIT: Just looked at my .pdf manuals and one is a SP-155 and is 21 pages and is only for operations. Also have a SP-155-4 that is 38 pages and everything from 22 on is a complete parts breakdown of the whole machine. I also have a printed copy but not sure what rev that is.
