Singer sewing machine dating by serial number
If you can find one in its original case and with the accessories, it will be worth more than just the machine. These are considered by many collectors to be the best machines that Singer ever produced.
Most importantly, the machine was the first to have a foot pedal instead of a hand crank. It was black with a gold scroll design on the machine.
Within two years, commercial sewing machines were being sold powered by electric motors.
By this time, the company also was producing commercial zigzag sewing machines.
It was called Blackside because all of the parts, including the cover over the light bulb, were painted black. This machine could produce 4,000 stitches in 60 seconds.
The 301 was the first slant shank and needle machine.
This made it comparatively easy to use and inexpensive to produce, and "Singer" rapidly became a household name in sewing.
