So I would like the situation checked please. if the Britannia bogie hub is the same diameter with the same amount of spokes but a different rim profile to our Princess Coronation/Royal, we would like to make a blanket change to use the Britannia bogie wheel hub for ALL 3 locomotives. I have attached images of the correct Hub along with the part number.The three locomotives are now produced by HUA and so it should be straightforward to check the situation. Thanks.
