Millie,
There is something not quite right here. Singer was not making machines in China in the 1800s and they weren't using the sphinx decals until 1891. Why do you think this machine was made in China? Can we see a close up picture of it?
If it is a Chinese made machine then you can't use the Singer data to date it. There is no dating data for the China made machines from the 1980ish era.
