This lovely yellow and red single decker is a 1950 Albion Valiant CX39N, with a Duple C33F body. It was originally operated by Hutchison of Overtown.
The bus was sold to Tuer of Morland, (near Penrith). Later, it returned to Scotland, and operate as part of the Highland Bus Service.
At this point, I can't find any specific routes in which this bus was in service, but I'll delve deeper later.
