What is a peeler? Today, British police are commonly called "Bobbies’," but originally they were dubbed "Peelers," both names being for Sir Robert Peel (1788 – 1850) who established London's police force in 1829. His officers wore blue tail coats and black top hats, a uniform that was deliberately chosen to ensure they blended in with ordinary folk. Each man carried a wooden rattle to raise the alarm and a wooden truncheon......but this figure carries a sword. Does this rule out his being a policeman?
Seems that wooden truncheons and rattles were not prerequisites for peacekeeping then. Some of the men who kept Britain's streets safe in that era carried steel. The sword-carrrying gentleman alongside is a Leeds policeman of between 1836 and 1860. Notice his tall black hat is like the hat the figure wears.
Midshipmen in the British navy of that day were largely sons of professional men, as well as members of the peerage and landed gentry. Even Prince William, later King William IV, served as a midshipman in his youth. I have spent hours down the rabbit hole of naval uniforms, and I will spare you the details. Suffice it to say that the figure's hat is consistent with him being a midshipman.
The prints below shows a midshipman of 1828 (left) and 1830 (right), and, like the figure, he has a tall hat and a sword. But, unlike the figure, he wears a coat with long tails. Images courtesy of the National Maritime Museum, Greenwich.
I can't attribute this sailor to any specific potter, but I have noticed a small number of figures on similar bases, and I strongly suspect they too are of the 1830s period and from the same pot bank.
