Saw this while watching The Sweeney from Heart and Minds episode staring Morecambe and Wise. A 76 yellow and white Devon takes a staring roll. Look out for the drifting but it ends with a horrific ending for the bus. They fill the box sections up with water!!!!!
The episode is available here: https://www.dailymotion.com/video/x3o9uew Brilliant to rewatch - you've got the camper (all too briefly), no mobile phones, period clothing, coppers who look like coppers, and in this episode Morcambe and Wise. It just doesn't get better than this.
