Antique mortise locks made for use with antique doorknobs and skeleton keys, made by Corbin, Russwin, Russell & Erwin, Norwalk, Penn Hardware, Reading Hardware, Sargent, and other manufacturers. The faceplates of the locks have been stripped and refinished; most will be dark brown to black, with some interesting color variations in a few (see photos for examples). Sizes of these mortise locks will vary slightly by manufacturer. The locks are in good working condition. Please allow us to choose for you; if youâ€™re ordering multiple locks, we will try to ensure that all the locks in your order are identical. Please allow 1-3 days for refinishing. At checkout, if ordering multiple items, please select FedEx Shipping instead of Product-Based Shipping to obtain an accurate shipping quote.
