fantastic work Ron,
sorry if its been asked before, will you be doing the whole roof, a freind of mine is building Liverpool lime st in 4mm and has decided to have a few sections removable/open to allow people to see in, I think having the entire roof would be good even if its only practicle to use it when taking photos etc.
Ive
often wondered if the roof at Manchester central shared any design similarities with the now demolished roof at Liverpool central, as if a model were to ever be made, someone could take info from the surviving roof at Manchester
look forward to seeing more pics
cheers
Mike
