In the 1990s and early
2000s, a number of former Lothian Region Transport buses
operated on the streets of Edinburgh, for one day during each
summer, known as the 'Edinburgh Classic Bus Running Day'.
I believe that the
first two photos above would have been taken during one of these occasions.
Now, these buses and
many others can be found at the Scottish Vintage Bus Museum at
Lathalmond, near Dunfermline, in Fife.
