The outside cylinders to drawing D27-10777 were fitted to 132 locos. As far as I am aware there were no problems with them. What is this mysterious modification that is not on the drawing? Has someone decided that an item fitted in the top of the steam chests on the Lizzies and Duchesses should be fitted to 45551? Why? Over to you, Patriot team. Can someone tell me at what stage of a frame build at Crewe Works was the mill scale removed?
