Incredible find there Paul.

I'll be keen to check them against the measurements on my illustration posted earlier.

P.S. Perhaps your disc is a 20" Rover plate? I should imagine they would fit reasonably comfortably. And the O.E.M. "Big Bob" and Supaswift plate (Part #900172) might also be a "fit". I did come across one generic "unbranded" blade plate that looked like a very good fit, as it had the 10mm centre hole and the outer holes were just over 300mm from the centre, but for some reason I can't find it again. I will post it up if I ever come across it again.
