The R. J. Sellick collection is available online from the NRM [http://www.nrm.org.uk/ourcollection/photogallery?group=Sellick%20collection here]. The collection features many photos of the pre-preservation SVR in the late 1950s and early 1960s. The photos are all freely available for non-commercial use with CC-BY-SA-3.0 as long as the original source is attributed - this can be satisfied by an attribution note on the file page similar to:
'''<nowiki>From the Sellick collection, hosted online by the National Railway Museum. [link Original Source]</nowiki>'''
Note that the NRM descriptions contain numerous errors, mostly minor.
