I bought an ex GPO Morris 1000 van in the '70s - at least I think they were still the GPO then. It had any covered 19,000 miles if I remember correctly, the paint on the floor was still shiny. I paid very little money for it, primarily I think because it had no synchromesh on second gear but apparently that was common. The speed had been restricted by a plate with quite a small hole in it between the carburettor and inlet manifold, presumably because the GPO in their wisdom thought they were to fast. This caused the drivers to run it up to full revs in 1st then crash it into second before they lost the revs.
I went to my local BMC dealer in Axminster and obtained a new 2nd gear, synchro ring and gasket set for the princely sum of £5.00. I removed the restrictor plate of course. Having fitted the parts the van ran beautifully. I resprayed it yellow and white, as I had the previous one I had in kent, found a nice comfortable pair of seats at the breakers, fitted side windows and some sound proofing and carpets.
I ran it for some time until colour TV's came on to the market, I couldn't get many in a van that size so I bought an ex British rail Bedford CA minibus - but that's another story.
