The same shape in two numbering series; Early Series 213 s (left) with Later Series 52
The 'M' suffix here appears to denote Medium size, not its usual meaning of applied decoration.
No example is recorded. 213 M is known only from this illustration in a sales brochure of F.R. Barlow and Sons who were Premier's wholesale agents.
In the brochure it is labelled 213 MH, the H denoting 'Handle'. In the brochure every shape with a twig-handle is suffixed 'H' but on actual recorded examples with handles the 'H' does not appear. (It does appear, however, on some Later Series pieces).
