A little further research confirms the crane in my pics above as LMS MP4 (BR RS1005/50, ADRC95203) a Cowans Sheldon 36t (50t) crane of 1930. Unfortunately I've failed miserably to find any further photos but she's effectively the same as the cranes preserved at the Midland Railway Centre and at Didcot.
