I just got this new singer sewing machine that I cannot identify. It has the no 0932277 on the front, which according to singer database is from 1872. But this machine is in an amazing condition and comes with a wooden box. Has a sewing motor and light and works. There s also a different serial number on the sewing motor (2267381). Can this be an upgraded 1872 machine?
How much is it worth?
