Here is the Dartmouth Corporation seal that appears on the Royal Charter
that Edward III
granted the city in 1341.
The King wanted to reward Dartmouth merchants for supplying him with ships
of war for his military campaigns in France. Fittingly, the seal depicts
the King riding in a cog (merchant ship) typically used at the time. Note
the image's similarity to the gold noble
of Edward III.
