October 1961
From internal to external tank.
12 months after the estate launch there was a major change to the model, as it adopted the van-style fuel tank located underneath the car.  From here on we refer to "external tank" cars.  Consequently the filler cap moved to the moved to the lower right hand side of the car and the boot floor pressing was revised.  The battery was moved from the boot to underneath the rear seat, on the right hand side.
