The Arms seem to be those of Vessey:
Arms: Ermine on a cross Sable five martlets Or
Crest: An arm embowed and couped at the shoulder erect from the elbow habited Gules cuffed ermine holding in the hand proper four leaves Vert.
The hatchment was made by Winsor & Newton of London and is just 14 inches by 14 inches which is somewhat smaller that the usual. I could not find it listed in the Hatchments of Britain. These last two factors might indicate it was a “sample”.
