I need help with a divided dish!

[Andrew Grover]

Can anyone tell me when divided dishes first appeared? I'm guessing 1918-1923? I picked up a clear divided dish yesterday  for .99, in near mint condition. It was in the 100 series - I believe 197? I do not have it in front of me, it's still in the car. I'll try to post a picture this evening and also make sure I have the correct number, or try to determine if it could possibly be a mismark.

A 197 is normally a a 1 1/2 qt oval? When I looked for information online I do not see it listed in any early Pyrex catalog. It has the double dollar sign and is marked on the rim. The dish also has the older PYREX print on it. I will post pictures. I hope they might be able to help. I love to collect the clear, as it is my favorite, but I do not know of a one stop place that discusses it. Thank you! 
Regards,
Andrew Grover

A round divided #130 (9 3/4"), was from the early 20's so it does make sense! Might be the stamp was a little smudged.

I don't know if you ever found anything about your dish. I have a couple of pieces of early pyrex and have found these pages very helpful.

I think your dish is on this page.  It retailed for $1.50 in this circular from 1931
