Christopher Buck Antiques Ltd. has dated this piece to the 1850s.

It is rare to find genuine long sets of chairs from this period (more than 8).
They are straight out of an idyllic Georgian rectory in the Kent countryside and are un-restored. Upholstery is generally good; probably about 20 years old with a number of light marks and stains.
There is some variation in colour of polish throughout the set.
