Does this shape appear in other series? Yes - Early Series 196/7M. In the Later Series, 13-7 is similar but undecorated.
In the Remued Early Series, suffixes were added to distinguish between size variants and between decorated and undecorated versions,
but in Pamela numbering there were no suffixes. Each variant had its own separate number. Pamela Series 2, 9, 11 & 13 all became Remued Early Series 196, suffixed 196/4M, 196/4 196/7M and 196/7 respectively.
This shape is the larger of two sizes in the Pamela Series, decorated, its equivalent undecorated version being Pamela Series 13.
