Hi all Responders to my request
Thanks for the response to my request. I have now collected a couple of hundred photos of locos surrounding the shed and can approximate sizes. Approaching Rotherham and Sheffield Library and NRM are part of the investigation plan. Photos from inside the shed are a particular requirement as these seem to be on the rare side, compared with the outside photos, which consist mainly of trains with the shed as a backdrop. Once again thank you for taking the time to respond.
Kind regards Mike
