This particular page of shape book 'B' is a bit of a mess. Later Series 160 is a jug, in different sizes. The glasses have been added piecemeal in whatever unused space was available on the page. The shape books show three sizes of jugs, numbered 1,2 and 3; and four styles of glasses as pictured (labelled "cheap"!).
The table headed "Turning" shows hourly rates of production. Allan James reckoned on throwing 48 jugs per hour, by hand, just 1 minute and 12 seconds per jug.

Height; 10 cm.
Judging by height, these appear to be the 'No.1' jug (left) and 'No.2' (right)
