This is the UK Gowland &Gowland Series Two.
It is not a Revell Highway Pioneer Series Two box.
In the USA, the Bentley was numbered higher than the Series Four , the Foreign car series in the blue boxes.
Someone deleted the proper USoriginal issue which had a separate box and wrongly repkaced it and many of the other 35 original boxing with the ten car gift set boxing.
That was an error which will take an extended effort to back out.
