This is a fascinating film of steam locomotive manufacture from A to Z in 1949. View in full screen by clicking on the double-arrow in the lower right-hand corner of the video. Have audio full on also. Note - the film is 38 minutes long. But who is counting when it involves STEAM LOCOMOTIVES. LOL [video]http://ssa.nls.uk/film/1276[/video]
A neighbor sent me the link. He's active on an international O-gauge three-rail forum and one of the UK members posted it.
