HAve just purchased a treadle singer machine. It has no drawers and sits on a wood base. HAs a 62 in very thin looks like leather cord for wheel to work. I need a new cord. Has 5 holes on top for round brass rings to fit in. HAve brass rongs. HAs a bullet shaped bobbin case. Can you tell me the year ? On a metal plate on top says Patented July6,1880, Sept 22, 1885 Aug 21 ?, and Nov18,1890. Thanks for any info. Sue Fountain Email address dave sue@ casair.net
