In the meantime, take a look at this bus, which is of the same type as Niddrie's Biscuit Tin.
It's a Morris Z no: TW6936 of 1927. Try to imagine it with NIDDRIES on the side and full of happy schoolchildren all singing the 'Niddries Biscuit Tin Song' (the words of which will be featured here shortly, by the way).
Ann Hough tells us that the NBT was painted blue, incidentally.
And here's a link to Dick Gilbert's fascinating site:
