Well to be honest I am a little worried about the whole idea. I have a tendency to ruin my good models with half arsed textures.
I am going down to Portsmounth this weekend to have a look at the real thing and just take loads of digital photo's. These will be the basis for my textures.
I'll just have to do one texture till im happy with it and then move on to the next.
Any suggestion would be great though.
