Oh, by the way everyone, I dug the Commer out of her grief pit at the weekend. After a quick tow start to free the seized up drum brakes and clutch, I'm delighted to say I soon had here flying up and down the road. The starter motor has packed up (£22 exchange for a new one) and the speedo cable snapped so i couldn't see how fast (slow?) I was going. But oither than that, everything seemed pretty much ok. Next stop, MOT station....
