I found this Singer Sewing Machine in my grandfather's belongings after he passed which I believe came from his antique shop that he owned decades ago. It has a motor attached to the machine and on the motor it says patent pending. There's also a serial number on the Singer Machine and after looking up that number it seems that the sewing machine was made in 1919. However, I can't seem to find this exact machine online so it's hard to determine the value of it. The serial number on the machine is G7272118. The serial number on the patent pending motor is 2022236. I could only get one picture to upload completely. Not sure what I'm doing wrong.
