I need some help in dating pyrex mixing bowls

[Former_Member]

I have 3 bowls with Crazy daisy, Spring Blossom pattern-the smallest bowl 401 is avocado green-bottom reads PYREX-for oven and microwave no stove to or broiler -Corning N.y. USA-the second bowl 402 is a lime green colour-same on bottom as #401-the larger bowl 403 is lighter then #401 - bottom of bowl-PYREX-by Corning -Corning N.Y. USA -baking and microwave. I have seen where the lime green is part of Spring Blossom 2 set. Are these a true set-should there be a larger bowl 404? Thanks

It sounds like you have the spring blossom green redesign. Which was made from 1979 to 1981 (the original spring blossom was 1972-1978). The set did not include a 404.
Hope this helps.
I found this info in the pyrex passion guide by Michael barber, that I just got today :)
