While your attention is on this subject Allan, could I please ask if this principle was also applied to limited edition Studio pieces?
I ask, because I bought a beautiful deep-footed charger, which I have seen listed as a limited edition (of 250) design. There is a fairly obvious "flaw" - the underside of the plate has a big sort of saggy bit, where the glass hangs down a bit, so it's uneven, not perfect. It is unmarked. I actually have another charger, same design, but different shape, also unmarked. I can't find any flaw, but I know that Caithness is incredibly fussy about perfection!
I would suspect that these are seconds. Should they have been destroyed?
