Finally, after what seems like years (ok, so maybe only a few months!), I came across two new thrifted Pyrex pieces for my slow growing collection.
The smaller one is the #474b, which is listed on Pyrex Files as an unknown pattern, and the circle dish I can't seem to find any information for. On the bottom it has the circle with 10 PYREX (TM) OVENWARE.
Hope you're all having a great Pyrex hunting day!
