For information on patterns and other research questions, search the Pyrex Potluck Pattern Library, see the Pyrex FAQs and linked websites, consult the Ask a Librarian database for Pyrex questions that have already been answered, and visit the Research Room.

The 167 would refer to the casserole's catalog number, with 167 being a round 1 qt. In 1926, this number was changed to 622, so presumably any dishes number 167 would have been produced before 1926. According to Pyrex researcher, Dianne Williams, these were produced between 1916-1925. Covers were often sold in this period with etched or engraved patterns on the top and flowers were a popular design. I'm not aware of what the letters AE-A designate, but checking with the collectors' groups who are very knowledgeable would be a good idea. There are many groups out there---here are a few: http://iantiqueonline.ning.com/group/collectingvintagepyrexglassware
Good luck and if you discover the meaning of AE-A, do let us know by posting a comment here.
