The Jug, although it matches the style of the pot and was made in same year, is different due to its low lid; raising doubts as to whether it was intended as a set. May even be a tea-pot itself.
Provenance
Made for George Baillie and Lady Grisel Baillie of Jerviswood and Mellerstain whose arms they bear; their daughter and heir, Rachel married Lord Binning and the plate descended in that family.
