Colonial American hardware was initially all wrought iron made by local blacksmiths. Even screws were handmade. Brass hardware was imported and was considerably more expensive. Undersized doorknobs were commonly used to conserve brass. Detailing was plain with the occasional turning of a doorknob foot.
Not compatible with pre-bored doors.
