A Saurer by any other name

For many years the Swiss manufacturer Saurer also built almost indistinguishable vehicles badged as Berna but over the years that nicety was dropped. However the town of Olten where they were made continued to take them into the local bus fleet. By the mid-Seventies Swiss urban undertakings were having to paint their buses a rather boring universal orange and white but many buses like the blue and cream 1964 Berna behind managed to escape it. By the time this view was taken in 1990 operators could choose their own unique colours once again but quite a few like this town were quite content to stick with orange.
