This round clear glass casserole dish LID is marked JAJ England. This is pre-owned and used.   The edges of the handles are rough as some of the JAJ Pyrex are known to be. There is also a chip on rim as seen in close up in photo #2. Other than that there are superficial scuffs and scratches consistent with age and usage.

Inner rim diameter is approx 7" and from end of handle to end of handle measurement is approx 9.5". The classic JAJ stamp is on the top middle of glass lid. There is a marking on one of the handles which is the number 21.

This among other pieces were given to me by a friend when cleaning out his elderly parents basement. Other than the research I do, I don't know much more about their history... Being a military family from the 1960s through the 1990s I know they traveled a lot.
