Sorry for nit-picking but...
I'm just watching the first episode on ITV player and Susan says her husband works for the Department for Transport. Wrong! It was the Ministry of Transport back then, it didn't become the DFT until the 1970s. The MOT test was introduced in 1960 so if it had been the DFT in 1952 we'd be taking our cars in for their annual DFT.
*sigh* I'm turning into a very sad, grumpy old woman, lol.
