405 (Early Series)    Bulb-shaped vase, dimpled, with 4-way mouth.

Does this shape appear in other series?   Yes - 500 Series 525.  Also 'A' Series / Kerryl A68

Only one size is recorded, 405/5, but the use of the '5' suffix suggests that other sizes might also have existed.

   Height; 13 - 13.5 cm.

An example mistakenly incised 485/5. Two such examples are recorded, both in the same handwriting, probably both done at the same time.
(Such mistakes did happen. For a selection click here.)

'W' Collection
The same shape in two different numbering series.
