Antique 2lb James Keiller & Sons Dundee Marmalade pot #1

An antique white ironstone 2lb preserve pot, decorated with a bold strike of the iconic black transfer for James Keiller & Sons Dundee marmalade. The underside bears the impressed Maling maker's mark.
This listing is for the shortest pot on the far left of the group picture.
Dimensions:
9.6cm diameter 
13cm tall
Condition:
The pot has an area of surface glaze crazing lines, to the left of and above the transfer. One of these lines runs over the rim and looks like a hairline, but is in fact under the glaze and a striation not a crack.
There is a glazed over chip in the underside of the foot, which will have been a manufacturing fault and not damage.
