Hello Cheryl, OH YES, blame it all on me. ;D
Yes yours is a four quart size. I don't much blame you though. You hardly ever see these with all the pieces. So if I seen it and the price was right, even with what I have, I'd have bought it too. I was at a flea market this summer and got an extra small plate for the four quart size for two dollars. Why I bought it, I don't know, I sure did not NEED it. :-/
