Got a job done that I've been meaning to do for quite a while. When I built the goods shed I built it from my own drawing from my own measurements of the real thing, The canopies were added as the track side one is in the background of one of the few photos, the main subject being the train, the road side canopy is based on NER practice and other similar sheds.
I never really put much thought in to a chimney, there isn't one there now and had no idea where one might be. This was until I found this photo a couple of years ago.
I started out with an unidentified grey moulded chimney that was about the right size and height, the angle was corrected for the shed roof.
It was clad with brick plasticard and a whitemetal pot fitted.
