Now I finally understood what TIB1186Z meant by blue top on
SBS0847A. Normally, the Mk3s (or any other single decked buses)
have their roofs painted orange, even those with full body ads.
However, the roof on SBS0847A is strangely, sky blue in colour.
Even the aircon unit is painted blue. The blue is similar to the
blue roofs that you see on Comfort buses. All the time, I was
looking at the roof from the inside until today.
