This is an 1807 J. Henry Contract Flintlock Pistol which has been converted to percussion and certainly seen better days.  These 1807 guns were used up during the War of 1812 and are today very difficult to find.  This one has lost a part of its forearm but still retains very nice lock markings.  There is a sailor's heart tacked onto the wrist of the stock and it does look like a belt hook may have been mounted on it.  I guess it could actually be one of Henry's Navy contract pistols.  As you can tell, it will need a lot of TLC. SOLD!!
