Ray the Forth Road Services Albion with angular cab built by Walter Alexander Coachbuilders is a Clydesdale model and common ly known as a “Snocat” when having this cab fitted. Caledonian Road Services also had some. Walter Alexander was on the board of both companies. I believe they were cold and uncomfortable hated by most drivers. The other Albion shown is a CX model.
