ID Bench Grinder/Linisher

I bought a 12 ton hydraulic shop press locally at the weekend and after a natter with the owner who was selling off a lot of his late fathers stuff asked if I could do with a polisher for nix. Sure I said thinking a small Ozito car polisher or similar and then he trots out this... I bought a multitool linishing attachment for my Abbott & Ashby bench grinder a few months back secondhand for $80 so I was pleasantly surprised. My question is, what brand is this grinder? The original manufacturers plate has long gone. It looks like the switch has been "modernised" and is not original. I'm thinking B & D, McMillan, GMF maybe??? Anyone?
