I have a bowl signed CP Kimberley, with a Webb etched mark. The Webb sig. is pretty blurry, which sometimes means a fake, but I haven't seen anywhere near enough of their marks to judge.
I know Kimberley worked at Webb 1930-1978 (thanks to Ivo's book!), but wondered if his is a well-known name.
...Huh! I just looked up the name in Hajdamach, not expecting to find anything, and the chapter on copper wheel engraving starts with a photo of him engraving a rock crystal goblet with bosses! I guess he is fairly well known. So maybe my question should be, is my bowl a real Kimberley, and is it valuable (i.e., more valuable than a Webb piece not signed by anyone)? I don't normally ask questions about value, but with this I'm pretty curious and clueless.
