Thanks to Ed Carter for the memory jog.
This image from our '87 UK trip shows that we did indeed visit at least the Beatle City building.(Still unsure if it was open at the time)
As far as the MMT bus goes, as far as we can tell the Beatle City version is the one from the movie. It was used for motor tours of Liverpool.
