Rewind. I bought two more yellow 501s off eBay thinking I would pick the best two of the three to keep with my almost finished Daisy pattern collection. An important lesson in Pyrex colors here. The one in the middle is the original one. I'm calling the two new ones Daisy, and haven't decided if the middle is Verde or just old. It has a fully fluted lid and the straight lines backstamp like the other two, so I'm leaning to Verde.
Luckily, the two new ones are perfect (10/10).
Anyway, a lesson in how not having the different shades side by side to compare can make a positive ID in the wild difficult.
A 400 set, a 440 set, a 470 set, a 480 set, a 500 set, and an 063, 043, and 045. There are also some juice bottles and serving pitchers with citrus that were part of Daisy, and a 3-piece bakeware set, plus some 700 pixie casseroles in bright yellow that match.
Of the main pieces, I need the 063, the 440 set, the 502, the 475, the 402 and 404. And maybe the 470 and 480 sets with the opal lids. All mine so far are the clear.
