Heydays Antiques has dated this piece to the 19th Century.
There is a Sarah Gadsby listed as 1835 and an R. circa 1849. As well as other Gadsbys in the surrounding area.

In one of the Photos you will see a label for Bell & Sons, who have confirmed that in 2005 a Mrs Gadsby Stored this Clock with them. As this Clock came to me from London, maybe she moved South? Either way a Gadsby owned this Clock at that time - Happy Families.
