Hello Paul and vcomm
I wish I knew what year the 'orange' Rovers was introduced.
Perhaps 1979 was the year? I had thought it was early 1980s.
The Powermaster for Grace Brothers is new information and one that helps
us in piecing together the Rover store brand story for this model.
So far, we have Chandlers, Youngs, and Grace Bros.
I note the subtle differences on the handle labelling.
"Super 4" for Chandlers; "Ball Bearing Wheels" for Grace Bros.
Paul, the video is a great resource for the record. Thank you.
Thanks and cheers.
