Richmond Road site
There's a bit of confusion here about the Richmond Road site; the YMCA and the playing field in front of it formed the Hawker Athletic & Social Club, not the site of the factory. The factory was on the other side of the wall on the northern boundary of the social club, entirely within what is now the housing estate.
Strange that there was no mention of the Hunter. It was the money made from that hugely successful fighter that paid for the rather elegant façade on Richmond Road. A couple of hundred Hawks also rolled out (or rather were driven out on the back of a flat-bed truck) of that factory!
