The shutter in the closed position fits within the window casement. This was the prevalent approach in the Colonies from New York and south. An advantage is the additional security because the shutters can not be lifted from the pintles in the closed position. A disadvantage is that the shutters must be matched closely to the inside dimension of the casing and the shutter rabbet should match the thickness of the shutters.
Any surface mounted hinge and pintle can be used, assuming there is sufficient width to the casing to accept the pintle. The hinge has a minimal standoff and the pintle would have the same matching standoff. Together an offset of 1–1½ inches will hold the shutter at the same distance from the structure and not quite parallel to the wall.
