I'm the same age. Birthday with a nought in it, this week!
I lived elsewhere in the country. No idea of the fleet but when the weather was too foul for my walk to school and I was feeling flush, I stumped up 10p to catch the Stevenson's town service to school or the PMT (aptly named) service to Stafford, which passed the end of my street, on the way home.
