Don't think you will find any shop like that on Bond Street!
However I seem to recall someone mentioning a shop in Knightsbridge round the corner from Harrods
and Beauchamp Place comes to mind.
Actually there is a store on Bond Street that has had pre-owned B/Ks in the display recently. I don't remember the name or exact location, but on the same side as Hermès, and North by a fair bit for sure.
