His red coat has navy blue facings and gold braid with a gold epaulette and black buckled cross-belt.

Although unsigned, the portrait can be firmly attributed to the Irish-born artist Adam Buck. It is set in an attractive rolled gold frame with a chased border. Under magnification there is light dust under the glass and a little wear to the paint along the outside edge. The brooch pin has been removed.

Adam Buck (1759-1833) was a portrait painter, print-maker and miniaturist who migrated to London around 1795 where he acquired a fashionable clientele. He is best known for his idealized images of mothers and children; these were readily available during the early 19th century as prints and so became popular templates for young ladies to copy in needlework and watercolour. He exhibited miniatures and watercolour portraits at the Royal Academy between 1796 and 1833.
