Mixed lot of 10 clear glass custard cups made by Pyrex. They all have the earlier Pyrex mark on the bottom which is just the name in capital letters with the "R" trademark and Made in USA.

--One is from the 1940s and has the straight rim (no scalloping), marked 6-11. Measures 3 1/4" in diameter across the top and 2" tall.
--3 are from the 1950s (after scalloped edge was introduced), marked #462 (5 oz) and measure 3 1/4" in diameter across the top and 2 1/4" tall.
--6 are also from the 1950s (scalloped edge) marked #463 (6 oz) but are slightly bigger in diameter at 3 3/4" in diameter and shorter at 1 3/4" tall.

All 10 are in excellent condition with no chips or cracks and not much scratching.

Late addition: also including early opalescent custard cup made by Fry Glass (subsumed into Pyrex), 2 1/2" tall by 3 1/4" in diameter, marked on bottom "Fry Ovenglass", made in 1927 with model numbers that are hard to read, good condition with no chips or cracks but some roughness around the inner edges
