Does this shape appear in other series?  Yes -  'A' Series / Kerryl A106 and Kerryl 'B' Series B3&B4 

There were two sizes, suffixed s and L

The 'H' values in this shape book entry appear to be the height of the basket body, not the body plus handle.

The details at the bottom of the shapebook entry
eg "Making  36" refer to production rates - per hour!  Potter Allan James reckoned on throwing 36 basket bodies in an hour. The figures were used for production planning, and costing.
