Chris, The article I mentioned is in Back Track Volume 20 No. 9 for September 2006 which can be purchased via this link:

It seems that it's No. 74 that's preserved rather than 72 as I had thought. The image I posted probably dates from around 1950 but that's only an educated guess.
The article isn't exactly complimentary about the NCC's 4-4-0 locos and reckons that the LMS era moguls and 2-6-4T's knocked them into touch where performance was concerned. The author also notes that the last U2 (No. 74) was withdrawn in 1963 but that the UTA (successor to the NCC) had been absorbing cascaded GNR(I) 4-4-0's for years and that they were better performers than the native ones.
