Finally found the M-Plate today after several months of boy looking. Confirms that it used to be a right hand drive delivery van with a sliding door on the left. It's paint colour was originally neptune blue with canyon brown leatherette (?). It's birthday is the 7th September 1978 although it's listed as a 1979 model. It must have had a camper conversion at some point. I feel more at one with my bus now!
i've never found mine, the panel behind the passenger seat was cut out before i got her to fit a captains chair
It was under the dash on the top of one of the heater channels. Only really saw it when I removed the glove box. Woody Lubber, I have a panel behind the driver's seat but it's not the m-plate. Some sort of other production plate. Worth looking at the heater channels at the front. Finding it means that the front hasn't been replaced as I previously thought. Whoever did the spraying though must have been on something judging by the number of colours I've found on the bus!
If you guys have spotted yours, I may have to go up for another look on mine. It's a '75 but the l/h bulkhead was cut off for a captains chair as well so may have gone. If I apply for a birth certificate will VW tell me all I need to know?
