Personally, I have a deep seated love for the P-series era of Corningware anyway, so I only collect pre-1972 pieces. It helps that the Petite pans, Pie Plate, Roaster and Loaf pan retained their P-series designation, even during the A-series era, post 1972. Thus, there are technically MORE P-series pieces than there are A-series ones.
Thus far, I have been able to find the following pieces in Avocado Medallion......
P-43 petite on the corellecorner.com web site. Randy & Debbie mention the roaster and the loaf pan, along with 2 covered saucepans, but not the sizes, as well as a skillet and a petite pan (instead of both sizes).
The basic point, is that I don't think anyone knows for sure which pieces were actually made in this pattern.... I don't think they made the large roasters (P-21 & P-76) but you never know... As I stated, neither of the books mentions the Menu-ette set or the pie plate, so your guess is as good as mine.
As far as the A-series pieces go, I know that production included an A-1 1/2-B as well as an A-8 skillet (I have them for sale on Etsy right now.)
Where is your Corningware??
