John Cosens Flintlock Fowler - Made in London by John Cosens, this 10-gauge flintlock fowler bears the royal cipher of King James II of England. It was made in 1685, the same year as James II’s coronation. Charles II, James’ predecessor, bestowed the title of “gunmaker-in-ordinary” upon him, making Cosens a regular firearms supplier to the king. At a later date, it was in the collection of the Duke of Argyll. At the National Sporting Arms Museum in Springfield, MO.
