Yes, I've been watching that one as well. Definitely Clichy, but WHY that treatment of the base?
Maybe there was a bad bruise which needed removing, but someone obviously decided that rather than just lose a layer of glass they would do some fairly elaborate cutting! For what purpose, one wonders?
It does look quite nice I suppose, and it would certainly make it obvious that some 'repair' work has been done, as everyone would know that no Clichy would have originally been finished this way. That's the only reason I can think of.
I don't think the price will go as high as it might without the fancy cutting, which may put some 'purists' off. But it is possible to get a nice Clichy at a reasonable price. I only paid between a couple and three hundred quid for mine, and with £30 worth of polishing by an expert hand, it's now worth about £800 I'm told!
