Which Pyrex model numbers specify duplicate items?
When a product is discontinued, its model number might re-appear on a completely different Pyrex item years later.
Dry measuring cups, numbered 18, were available from 1940 to the early 1950s. From the mid 1960s to the 1980s, two round individually sized clear Pyrex casseroles were produced. The smaller one, a 10 oz (300 ml) size, was numbered 018.

From 1926 to the early 1940s an 033 was a clear Pyrex deep oval casserole. A shallow oblong 033 appeared in 1963 with Golden Honeysuckle, a pattern that is most notable for its distinctive casserole shapes. Both types of 033 have a 1½ Qt capacity.
In clear Pyrex, 043s were originally shallow oval casseroles, manufactured from 1926 to 1938. In 1956 two deep oval casseroles debuted in opal Pyrex and the smaller one was also called an 043. Both 043s hold 1½ Qt.
From 1926 to 1938 clear Pyrex square casseroles were numbered 053. In opal Pyrex, shallow oval open bakers, or non-divided dishes, were introduced in 1958. In company literature they were called 053, but it seems that they are never marked with a model number. Both 053s are 1½ Qt.
In the late 1910s & early 1920s basic round casseroles were sold without lids as pudding dishes. Company literature states that a 123 is a 1 Qt pudding dish, but this model number might not appear on the item. It corresponds to a 103 casserole sold without a lid. In 1937 a Matched Set combined a 123 1½ Qt Sweet and Low casserole with six newly designed thin-rimmed custard cups.
Until the early 1950s, a 212 was a 9 inch loaf pan. During the 1970s & 1980s a 212 was a 12 inch pizza pan, or Patio 'N' Pizza Plate. Being part of the Microwave Plus product line, it was also called a Microwave Cook 'N' Serve Tray.

From the mid 1920s to about 1938, a 213 loaf pan was individually-sized, holding about 1 cup and measuring less than 5 inches long. In 1953 the standard 9 inch loaf pan was updated with new handles and slightly different proportions. It was named 213 to distinguish it from the older 212 which was still on the market at the time.
Offered for a short time in the 1920s, a 220 cake pan is wider and more shallow than a regular cake pan. In the late 1970s, clear Pyrex souffle dishes were briefly produced in three sizes (½ Qt, 1 Qt, 2 Qt). The largest was available around 1978, and catalogues and packaging call it a 220, but it might not be marked with a model number.

Between 1921 and the mid 1920s, a 234 was a small biscuit pan, measuring 9-1/8" long and 7-5/8" wide. In 1980 or 1981 a 4 Qt rectangular utility dish was introduced. Also numbered 234, its dimensions are 15 x 9¾".
One of the earliest Pyrex products from 1915 was a 322 oval dish with handles, or au gratin dish. It was dropped in the mid 1920s. When clear Pyrex rimmed nesting bowls launched in 1942, the smallest bowl (1 Qt) was also named 322.

401, 402, 403
First seen during the late 1910s, clear Pyrex 401, 402 & 403 shallow oval dishes are meant for single portions. Older ones are 10 oz, 12½ oz, 18½ oz, and newer ones are 12 oz & 16 oz; the 403 was dropped. In opal Pyrex, 300/400-series nesting bowls are similarly numbered, in 1½ pt, 1½ Qt, and 2½ Qt sizes.

A 410 (3 oz, 3½ oz) clear Pyrex custard cup was manufactured from the late 1920s to the early 1930s. Opal Pyrex Hostess sets debuted in 1949, and the 12 oz bowl in that product line is also a 410.

A 414 was a 4 oz custard cup from 1932 to about 1945. In the 1970s & 1980s a 414 held 14 oz and was sold with plastic snap-on lids. With avocado green lids they were called Stackmates, and changing to rust-coloured lids in 1981, they were re-named Bake Mates.

Clear Pyrex 442 (4 oz) ramekins with flat rims were available from the mid 1910s to the late 1930s. Opal Pyrex Cinderella bowls were introduced in 1957 with a 1½ Qt size that is also called 442.
463, 464, 465
Round open baking dishes, or pudding dishes, offered during the late 1910s & early 1920s are comparable to uncovered casseroles. Among their sizes are: 463 (½ Qt), 464 (1 Qt), 465 (1½ Qt). First appearing in the mid 1940s, the most recent assortment of custard cups includes: 463 (6 oz, 6½ oz), 464 (9½ oz, 10 oz), 465 (15 oz, 16 oz, 1 pt). Although pudding and custard seem nearly synonymous, pudding dishes and custard cups are not the same type of item in Pyrex.
From 1916 to the mid 1930s a 502 was an individually-sized bean pot in clear Pyrex. An older one holds 1 pt and a newer one holds 14 oz. In 1948, a 502 became an opal Pyrex refrigerator dish with a 1½ pt capacity.
From 1936 to 1938, a 602 casserole was a shallow oval 042 (1 Qt) with scalloped handles topped by a 602-613 flat utility lid. During the mid 1980s the Microwave Plus product line also included a 602 oval casserole with a flat lid, but its shape and size are entirely different. It holds 24 oz (700 ml), and it is more like a rounded rectangle than a true oval. Most examples have concentric rings embossed on the lid.

From 1936 to 1938, a 603 casserole was a shallow oval 043 (1½ Qt) with scalloped handles paired with a 603-614 flat utility lid. During the mid 1980s the Microwave Plus product line also included a 603 casserole with a flat lid, but it is rectangular with a 1 Qt (1.2 L) capacity. Its size & shape seems to be the same as a Corning Ware MC-1 Fast Food Dish.

From 1927 to about 1930, wide-rimmed tiles for four different 1½ Qt casseroles could be purchased. A 723 round tile fits underneath an 023 casserole. Between 1937 & 1949 Sweet and Low casseroles (123) were topped by a pie plate shaped lid, which is also a 723.
