Small size Frank Cooper’s Seville Marmalade ironstone pot

A scarce small size marmalade pot from Frank Cooper, Oxford. Made of white ironstone pottery and decorated with a detailed under-glaze black transfer:
 
'Frank Coopers
"Oxford"
home-made
Seville Marmalade.
Warranted pure,
prepared only by
Frank Cooper,
Oxford.
(Registered Label)'.
 
A diminutive pot in a rarely offered size, larger than the single serving train size but smaller than the 1lb.
 
Dimensions:
6.3cm diameter 
7cm tall
Condition:
There is a small scrape on the rim on the back side, along with a small circular surface scrape inside. There is also a very small, faint hairline on the rim above the transfer, and some surface striation lines in the surface of the body to the left of the transfer, some of which run down over the foot with a bruise.
Otherwise the pot is in very nice condition, and displays very well with some light age related wear and marks.
