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. The interior half only option is to be ordered in conjunction with an "exterior handle only" door set. This option is made available for those who want a different style or finish on the interior and exterior of their entry door. A double cylinder will have two keyed deadbolts (one interior, one exterior) while a single cylinder will have one keyed deadbolt (exterior) with a thumbturn on the interior.
