British Clear Pyrex 
          
British Pyrex clear round casserole, 166 with S-266 lid
Round 166 (1 pt) casserole with S-266 utility lid.  In multiple sizes, casseroles with this shape were produced until the mid 1950s.  Aside from its handles, the body of the casserole is identical to an American 021.  Another distinction is the use of a utility lid on such a small casserole; in both Canada and the U.S., 021s were only offered with a knob-top lid.

         

British Pyrex clear 301 bowl
301 bowl, with embossed half-pint measures on the inside.  This size debuted in the U.K. about 1951, and it is the same size & shape as a U.S.-made 402.  Two larger bowls (302, 303) corresponding to American 403s & 404s arrived in 1952, but it seems that the 401 size was not duplicated in Britain.  All three sizes also became available with a coloured exterior finish in 1952.
