I've made a married covered casserole out of these early Pyrex glass lids in the photos, but the two pieces are actually separate oval casserole lids. The plain clear glass lid is the number 110 cover to the 10" oval baking dish, produced in 1921. Pyrex catalogs and advertisements of the time showed the handled dish on top of the nearly identical un-handled base but the two pieces were reversible due to no lip or rim on either piece - they rested on top of each other. This piece has the dollar sign impressed second mark at the center, differing only from the very first mark by the addition of the 1919 patent date.

The floral spray engraved wheel cut lid fits both the 1-1/2 and 2 quart oval casseroles. It's numbered 634 and 643. Engraved Pyrex was introduced in 1918 and continued well into the 1930s. This lid is in excellent condition with no damage, scratches, fleabites, etc. The plain side handled lid or dish has some mold line roughness to the rim edges near one handle and two tiny, barely felt fleabites to the inner rim. Price is for both pieces.
