Hi Andrew,
Superb work on the units and Cromptons, I remember the VEPs really well as they worked the 93 headcoded stoppers down my way. I only remember seeing them in blue grey though I remember the smokey orange curtains too, I think later on some were replaced with a grey ish colour but that may have only been in first class.
Pushers were common too and your 33/1 looks great I always thought they sounded better than the others.
I don't remember the class 71s except seeing some withdrawn ones at an Eastleigh open day.
Do you have plans to build a layout for this stock to run on?
Cheers Peter.
