Now, I can't really claim that the chair in the illustration is "new". It's news to me, but has been sitting in the Geffrye Museum (now known as The Museum of the Home) since 2005, and was part of Bill Cotton's collection. I simply didn't know it was there until today, when I was checking the museum collection online - a fairly new facility. In fact I found another relevant chair as well, but more about that later.
The chair is a standard Warrender side chair, apart from one feature - the front stretcher. Normally, chairs by Warrender have the double plain dowel front stretcher that we also commonly see in chairs by his nephew, Clissett, and his son-in-law William Cole. I know of just one example of a Clissett chair with a similar single pattern-turned stretcher, and a couple by Cole - all are the same, and of the same general form as this one by Warrender.
In fact, there are three identical Warrender chairs at the Geffrye. I shall try to see them if I'm ever in London again...
