Base incised 31m Pamela Handmade 1934
The 'm' suffix on this piece is anomalous. Pamela Series numbering did not use suffixes. In Remued numbering 'M' usually denoted gumleaf decoration, although occasionally it was used to denote Medium size and for this shape's Remued equivalent (Early Series 180) that was so. Either way however, its use here on a Pamela piece was presumably a mistake, made while Remued and Pamela pieces were both being incised at the same time.
