On the pistols: The one with the blonde grips is definitely a replica, it has Phillips head screws. See that cup-shaped thing on the side of each pistol? That is called the pan. You put gunpowder in that and it ignites the powder inside the barrel. if your pistols have a hole right above it, they are real and they are functional. The dark one looks to be the better of the two, and although it is probably a replica, it might actually be antique. Just looking at how both are made, the darker one might actually be functional, I doubt that the blonde one is. Take it to any gun shop and they can tell you all about it, including the age and origin.
