Anachronisms
I recently watched this series and it seems to me there are a few things in it which don't fit the time in which it is set. Firstly, when the lawyer wants Franklin Blake to burn the statement which Rachel wrote, he hands him what appears to be a safety match - I suppose this might just about be ok, but safety matches didn't really come into being until the mid-19th century, which is when the novel is set, so I wonder if they'd have been available in rural Yorkshire.
Secondly, when Rachel and Godfrey are due to be married, Godfrey carries two wedding rings - a man's and a lady's. The fashion for men to wear wedding bands did not come into being until well into the 20th century.
Lastly, from what I've seen in pictures, gentlemen in the mid nineteenth century were either clean shaven or had a full beard and moustache - the facial hair sported by Franklin Blake in this series looked far too modern.
If I'm wrong, do let me know - I'd be interested to hear whether these really are anachronisms.
