Right then Brian
I have given the wheel “a good stiff “lookin’ at” some good news but mostly bad……
Good news an S on the hub.
The steel ring holding the sprocket in place, with the three slot-headed, stepped shank bolts is very badly worn and thin around the holes for the bolts. This view shows the inner face.
The cush rubbers show signs of wear due to the movement of the steel ring how it caused this I have no idea.
