Hey,
Just read though and I see you need help with the water tender, 60019 water tender was 4472 flying Scotsman water tender and if you type 'flying Scotsman water tender' in google you should find pictures, also on 'BBC Archives' website there's a video of flying Scotsman replicating a non stop run to edingburgh and in this video it's shows the water tender from the top looking at the water filling point.
Hope this helps,
