Historical pair of guns for the daily quiz of today.

The pair of flintlocks shown in the picture were used in a duel between two prominent American politicians,  one, a former Secretary of the Treasury and the other, the sitting Vice President. The duel, which took place in the early 19th century, resulted in the death of one of the pair and ruined the political career of the other. 

The gun-maker was particularly well known for his high quality duelling pistols and in the 18th century England, his name was sometimes prefixed to "affair" to signify a duel.

Identify the gun-maker and the duel.
