Prosper Vallee is listed as being in Philadelphia from 1826 to 1840. The locks are signed "P Vallee". The Damascus pattern barrels are signed "P. VALLEE PHILADELPHIA" and have "R.H" and "1" between Birmingham proofs. "A" also has a dot on the plug and barrel at the breech, "LD" ahead of the wedge staple, and a string of four dots just behind the rib. "B" also has "FI" behind the wedge, "D" ahead of the wedge, and a string of three dots behind the rib. The same number of dots from each gun is marked inside the barrel channel of the stocks, and the "B" stock also has an "X." The breech plugs are engraved and have gold and platinum inlaid bands. The trigger guards enclose adjustable single set triggers and have decorative "pineapple" finials. The locks and furniture have primarily floral scroll and border engraving. The period wooden case has a brass lid plaque inscribed "H. Pratt McKean/Phila". There were multiple Henry Pratt McKeans across a few generations of the influential McKean family in Pennsylvania. Henry Pratt McKean (1810-1894), the grandson of Thomas McKean, a signer of the Declaration of Independence, would be the most appropriate owner of these pistols.
