Late 1800s or early 1900s vintage embossed metal door knobs and hardware, William Morris style, very lovely and ornate. These are original vintage architectural salvage doorknobs, antique, not newer reproductions.
These could probably be restored to working condition, though they aren't in working shape right now. (We have just the hardware shown in the photos, no keys for the locks.) They would also make great old hardware for parts, or primitive coat pegs and clothes hangers, etc..
