Try the Breakdown Crane Association... or wait until the owner of GWR No.2 happens by ('cos he is a WT member).
My apologies for not mucking in to this thread earlier! I have only just spotted it (alas I am unable to check all the forums as often as I would like).
The first photo in the thread shows RS1075/30, which ended its working life allocated to Cambridge. This is not recorded in Brownlie, but is verified by observatioons reported in Railway Observer at the time and now posted on the BDCA website.

The RCTS photo (http://www.rcts.org.uk/features/mysteryphotos/show.htm?img=66-59-12&serial=6) is the former RS1076/30, which was allocated to Shrewsbury and numbered 11 in GW style. There are records suggest that it was returned to BR(M) (and reallocated its original number) in Jan 1963, however there are photos of it at Shrewsbury in "the mid '60s" and the earliest photo I have found of it back at Crewe are dated August 1967 (it was withdrawn two years later from Crewe).
The Deltic photo (http://www.napier-chronicles.co.uk/13_4-7-79.htm) will be York's ADRC96709, not long after its conversion from steam to diesel-hydraulic power.
