Bench grinder with actual tool rests

Alex’s answer confuses me.

Any rate, I noticed last time I was in the 'Space there was another bench grinder sitting under the bench in the back. I did not note toolrests or not, but it seems like you could probably get/build some if needed.

Also noted that the wiki notes a Porter-Cable on loan with a photo of a lovely grinder with tool rests and eye guards. I’m guessing that’s a stock photo, but I wonder where that is?

Also, would overhauling the bigass grinder/polisher be an option, or is that unrealistic and/or ill suited for the purpose?

What about the belt sander that, it seems, needs to find a place in the machine shop? Could that be suited to this purpose? I suspect not, but I figured I would ask. It appears to have been alluded to here.
