Note:

The Solid Yellow Garage Door with Counterweights only came in 'The Building Toy' version of this set, released only in Great Brittain and Australia. So was the Embossed version of the 2 x 4 SHELL Brick. When 'Royal Dutch Shell plc' changed 'SHELL' to 'Shell' (before their Logo changed in 1971), LEGO changed the name in some items also, like for the Truck in this set. No actual proof was found though that the Pumps or SHELL Brick were also changed during production of this set.
