The Lancaster was NX611, and it is still alive and well as "Just Jane" at East Kirkby. NX611 was at Squires Gate for two years between 1970 and 1972 as part of a museum which really didn't get going. It reminds me of the Lincoln and Beverley which stood at Southend's museum in the 1970s; you could climb up to the towering cockpit of the Beverley - no nasty piles of whatever to keep kids out.
