Seller: outhousedoor (310) 100%, Location: Brimfield, Massachusetts, Ships to: US, Item: 303293794277 Several sets of toilet seat hardware - some are complete and some are partial sets. There is one end cap bolt with no mate - maybe you have a match. All test as brass - not attracted to magnet. But a couple of the threaded screw parts are iron - attached to brass arm knobs. Some are all brass. These came from an old barn on our property that was torn down. A family member had removed and collected this hardware from toilet seats over the years from about 1910 to 1960. Not sure of the dates of these sets - some appear older than others. Family hopes someone can use them for restorations.
