It appears to be a mounting bracket from a very old treadle sewing machine. It was at my great-grandparents' house. I believe it's a rare and unusual item now. Most items of this type are only found in existing condition. There are scratches, stains, rust, fading, and discoloration. How about it, sewing machine professionals, those looking for hardware, repair technicians, sewing machine enthusiasts, collectors, etc.? Please, those who need it, before its rarity increases further. Shipped via Mercari delivery. #sewingmachine #sewingmachinetable #commercialuse #treadle #showaretro #sewing #parts
