The key as Richard so succinctly puts it is in Para 30 of 112G.
However depending on how many vintage MV's and or Commercials any local VL office has in it's catchment area you may still find a problem convincing the counter staff that what you are proposing is correct. As a result I have over the years adopted a cast iron formulae for dealing with this situation, for what its worth here it is.
Take several good clear photos of your truck ie one side shot and one three-quarter front.
Know what your unladen plus payload weight is, you'll have to work this out in pounds from the literature and then convert this figure to Kg's, show all your work out and how you built up the gross weight and your source data, alternatively put the truck on your local weighbridge and get a stamped ticket.
Have all your paper work to hand in order of presentation; I always start off with the photos to set the scene.
If you still have the 'old style log book take that as well, the 1947 petrol coupon stamps in mine are always a talking point!
Last but not least be pleasant, these people are only doing there job and they have to deal with some right bozo’s during the course of a day. Don't get hot under the collar, if you are failing to get a result ask for the desk manager, smile and start again.
Some people can do all this at their local post office, I have to say I have never managed this and have always gone to the main VL office in Oxford, which since I developed this simple little system has been faultless.
