Unknown Currently under restoration. Note from the owner left on the photo page Aveling Barford and it's spurred me on to get on with the restoration. The canopy is currently being rebuilt and I've now straightened and repainted the canopy supports. I'm currently working on the tin ware and then I hope to get on with the body. The roller is a runner and we use it for repairs around the pumping station. It does smoke quite a bit so the injectors probably need looking at. Roy Barratt
