Vintage Burwood Word Clock - My New Holy Grail

I was innocently browsing through an old decorating magazine from 1978 this morning, when this ad jumped off the page and smacked me upside the head (click to enlarge):

Needless to say, these Burwood word clocks are now officially on my Holy Grail list. Especially that Tick Tock one - wow. I searched around online and couldn't find even a photo of either of them, let alone one that is for sale... they must be rather hard to find. Isn't that usually the way with Holy Grail scores though? ;)
