Dickinsons Antiques has dated this piece to the Georgian era.

The wood to which they refer is not the small yellow-flowered tree found so commonly
in suburban gardens throughout England, but a much larger species, Cytisus Alpinus, which
thrives in Scotland and was perhaps the most highly prized amongst the more unusual
cabinet- and chair-making woods.
