Double Barrel Derringer Pistol and Two Flintlock Pocket Pistols

Likely continental, first half of 19th century, all with walnut grips; the flintlocks with cannon-style smooth barrels, the larger one with engraved elements; the double-barrel derringer with rifled barrels and nearly illegible engraved writing on both sides of the lock, possibly Italian.

Largest pistol is 7-3/4 in. long

All pistols with moderate oxidation; the larger flintlock is not functional; the smaller flintlock has a frozen hammer; the double barrel gun is operable with a bit of metal loss to the right side.
