Singer sewing machine serial number G 0094450

This is a singer sewing machine, that I got at a garage sale, about two years ago. I almost right away noticed that it’s not just a sewing machine so I decided to dig deeper. The serial number is G0094405
I believe this machine is from the 1900’s but I’m not sure what year exactly. Maybe some of you can help me out, to identify it, I didn’t find much information about it online. I believe it’s a model 127K
If you know more about this machine or have any possible sites where I can ask professionals to help me identify this machine, I would really appreciate it. I love all things old and I’m so happy and amazed that I have this amazing machine in my possession.
