Singer Model 99 - The Original Portable Electric Machine

Find vintage genuine and quality aftermarket replacement parts for the Singer Model 99, introduced in 1911 as a more compact alternative to the full-size Singer 66. This revolutionary 3/4-size machine made quality sewing portable and accessible, and in 1921, the 99K became Singer's first portable electric machine.

History of the Singer Model 99

Introduced in 1911 to meet growing demand for a lighter, portable domestic machine that didn't require a dedicated sewing table. At approximately 22 lbs (10 kg), the Model 99 was significantly more portable than its full-size counterpart while maintaining the same reliable mechanics.

• 1921: Electric motor option introduced - the 99K became Singer's first portable electric machine
• Production Span: Continued until around 1958 with various improvements

Identifying Your Model 99
