I think that because there are several trays in the same or similar patterns it takes us back to the buyer choosing to make up sets to suit their own marketplace. Trying to catalogue sets sometimes doesn't work because of this mix and match option available to buyers whether wholesale or retail.
As to the damage around the edge of the lid and rim of the dish, this is usually caused by usage, picking the lid up and putting back on can and does cause flakes to be chipped away, and not all ebay (etc) sellers notice these or think they are worth mentioning. Cracks through pieces are more likely to be thermal shock, whilst when something arrives in bits like a jigsaw you can be sure it's either poor packaging or poor handling in transit. I always leave a package or even something I've bought from a charity shop in the packaging it arrived into come up to the ambient temperature in the house, before unpacking it. Then when washing it I do it in warm water not hot, as hot water can cause thermal shock as well, and cause cracks to appear in pieces that otherwise appear to be sound. Glass is funny like that - it's like it has an invisible crack which can suddenly become visible when the temperature changes suddenly.
Talking of new pictures, I've just added some unfrosted amber candlesticks to Reich 8792 gallery - the first time I've seen these!
