The Victorian collection by Nostalgic Warehouse is characterised by a distinctively pointed peak with a floral design, intricately detailed around the edges of the plate. The Victorian design is a reproduction (although slightly widened to accommodate pre-drilled doors) of Yale & Towne's "Largo" hardware from around 1910 and is in the Flemish Renaissance style. The style has been modified slightly to fit on modern pre-drilled doors. A mortised door is usually an older door that has a longer, more narrow lock body and can be used as a passage or privacy door set. To use it as privacy, you have a skeleton key that unlocks and locks from both sides of the door. To use it as passage, you would simply not use the key or lock the door.
