Mikkel,
Thank you, but I'm a bit of a bodger when it comes to photography. Thank gawd for digital or I'd be well and truly stuffed. All my presentable shots have been taken with a Canon 300D which is now getting on a bit in digital terms, but I do utilise two necessary extras - a Manforotto tripod and a remote switch. I've yet to get a decent shot with artificial light, even bright daylight bulbs and that worries me when it comes to taking future shots of Basilica Fields. I guess I'll be digging deep for some decent floods.
Back to liveries; you've made some interesting points.
There were a range of photographic emulsions on offer at the time, and yes, they were red blind, but - and it's a big but - not all exhibited the same properties. Going back to matters Great Eastern as I can at least speak with some authority without putting my foot in it, it is almost impossible to see the vermilion lining on +99% of all images which isn't too much of a problem on the ultramarine livery as one can see the blue and black border, but in the past it has caused much consternation with those locos painted black. Both Adams and Bromley's black locos had red lining, and after 1890 all goods engines were painted black.
An unofficial painting procedure has been handed down by the photographer and ex-GER employee Ken Nunn, and because of that one document it was long assumed that all black goods engines from 1890 were lined red in the same style as the blue passenger locos, but this lining couldn't be seen on the emulsions of the period. Only relatively recently have we come to understand, from other contemporary sources, that the GER infact pulled a fast one and lined only the lowliest of four-coupled shunters, and all other goods and shunting engines were plain black and unlined.
Here's an example of the difficulties encountered. This class of downright ugly ducklings was the first mogul (2-6-0) not only on the GE, but in the UK, and was painted black, lined red, and the cab side number plates were vermilion. See how difficult it is?
Back to Slinn's comments about black lettering; I simply don't know enough about the GW, or have the resources to hand to make too many bold statements. I believe a study was conducted to see if the eye can differentiate between red and black on these old emulsions, and the consensus was a resounding 'No', but I don't know if it was particularly scientific in its execution, and I think there is a lot to be said for gut feeling.
No. 59972 appears *to me* to have red characters, and both the running number and small GWR appear to be darker. I agree, this may well be down to the photographer touching up the lettering - ye olde photoshoppe! I hadn't made a connection with this practice possibly giving rise to the theory of black lettering, but that seems like a distinct possibility to me.
Thanks for your considered thoughts - they are precisely what I had hoped for.
