  1. Hi,

    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:

    Good luck and if you discover the meaning of AE-A, do let us know by posting a comment here.
