In the 1950's Singer brought out the first slant machine 301-the needle angled forward...it was slanted.
The 301 was just the beginning of a legendary family of Singer slant needle machines. It was followed by the 401A, 403A, 404A, 401G, 411G, 500A, 503A, 600E, 603E, & 604E, all of which used the same steel gears and direct drive motor.
