The chassis corresponds with your registration document, 1970,june.
The plate is not original to van, so details on plate are for the 1974/May van it was originally fitted to before being put onto your van, for whatever reason
.So these details are for another vehicle.
What is the engine number in van?, is it the same numbers as the last part of chassis no. on plate? ,Originally it would be the same as last numbers of chassis number on chassis itself but with a two letters at start, could the plate be off of the van that the engine fitted came from?
What your van came with fitted originally has been lost with the original plate.
