I do know what you are talking about PC but I don't remember the name of this place. I saw it on tv once where they have a massive warehouse of every piece of cutlery, dishes, teapots, etc. This place specializes in keeping the odd things so that when something breaks, they are surely to have the one.
The show had this women who had this antique tea set and one of her tea cup was broken. Now, this thing was tough to find but this warehouse found it for her. If only I remember the name....
Sorry Miss PC. I know how it is to have one less of something that belongs in a set.
