Antique open work wrought iron surface mount plate latch, late 18th to early 19th century with slide privacy bolt and marked on the latch A & F -WH. Latch measures 3 3/4"high x 4" deep and is accompanied by early original brass narrow neck knobs measuring 1 3/8" diameter with our own brass replacement rosette. This type of lock is not reversible and is right hand only. Knobs are currently spaced for a 1" door but can be modified for any door thickness - please add that information as a Comment when ordering. Latch is in very good working condition - spring is good. We have completed the latch with a keeper hand-made in our own workshop measuring 3 3/4" high x 3/4" wide and extending out when mounted 3/4". Complete with slotted screws.
