Japanese Belt Kit Announcement - I hope to offer, perhaps before year end, timing belt kits for the obsolete, discontinued Singer kits for the machines that were made in Japan. Belt kit 541207 was discontinued, but I do hope to revive it for models that I know of: 610U 615U 650U 680U 690U 698U, keep an eye out if you are needing one of these kits. 

Japanese Belt Kit Update: 1/09/19 Unfortunately  a work still in progress at the moment, but am closing in on it :)
