A Very unusual Yew Wood Windsor Chair c 1830

A Very unusual and Rare Yew wood Windsor chair firstly it has a blind back splat ( not pierced ), but also it only has three spindles either side of the back splat and it has never had any more, the underarm turned supports are quite well turned so i dont think it was made like this for cheapness, i am sure its from the north Nottinghamshire region, the condition is excellent and a nice colour and patina.
