1/2″ LD-K-10 Knob — a faithful, exact copy of a specific period original from the Londonderry collection. This hefty, cast-brass interior knob delivers authentic weight and historic detail in miniature: every contour and proportion is reproduced from the original pattern to preserve its antique character. Ideal for restoration projects or period interiors, the LD-K-10 pairs beautifully with traditional backplates and classic hardware schemes. These are the finest reproductions in the world, cast to order for uncompromising quality and consistency. Each knob is produced on demand—please allow roughly 4 weeks lead time (this is an estimate, not a guaranteed ship date).
