Factual error: A plastic bag of items is found under the footboard. Plastic bags weren't invented in 1969. They first appeared in public in 1979.
Factual error: Two vehicles in this episode date from after 1969 when this episode is set: in the first scene the Austin Maxi is a 1971 model, and the mobile library is J registered, which means it was first registered after August 1970.
Factual error: The Austin 1100 police car has a northern Irish number plate, despite being set in Oxfordshire.
Factual error: Some people are shown supposed to resemble the Skinhead sub-culture youth of the day. In 1970 Skinheads were heavily into Reggae and Tamla Motown music, which as we know were predominately black singers. Hence were not into the British Movement at this time. Secondly the wearing of jeans with large turnups were by "greasers" or "rockabillies" both of whom did not wear them with braces or Dr Martin boots.
