Sorry to hear that Brian, I do hope it is only a temporary condition, just the result of an infection, and that you feel better again soon!
I do appreciate the points you made as well Arun. There is indeed so little left of the former Isle of Wight interiors after the cars were stripped of asbestos, and as I am given to understand, precisely because of the risk of residual contamination. Any "restoration" effort would pretty much require starting again from scratch!
I suppose that an artist, or indeed modelmaker, has the benefit of being able to recreate objects or scenes otherwise lost for ever, but for me, I always preferred to start by getting the overall visual proportions as correct as I could manage - by doing "measured drawings" from life in the first place! Details could be added, or modified later, provided sufficient reference was available, but I found that the whole thing really needed to be built around a solid core!
Folks might be surprised, perplexed, or even horrified by some of the peculiar antics and "dodgy" positions I got into to achieve the right viewpoint sometimes?! For one interior illustration, I discovered that there were no seats left inside, and a completely rotted floor under a preferred window in the derelict carriage selected!. The only way to depict the scene from a seated passenger's eyeline, had me perching myself on a couple of found boxes - and all the while balanced on a wobbly plank over a gaping hole! Anyone catching me there and doing that would probably have had kittens on the spot, at the very least?!
That is partly what I meant by hoping to be "trusted"!
The end result was fairly well received at an exhibition though, was subsequently published in a book - and even I was reasonably pleased with it!
Pete.
