Although normally said to be a class 11, Director, I have a nagging feeling that it is acually a class 11a, improved Director.
62660 or 506 is currently at Barrowhill on static display sadly probably not to steam again at least for a good number of years.
35 of the class were built at the GCR, Kitsons and Armstrong Whitworth in almost equal numbers.
