What a treasure you have!
Welcome to the Quilting Board!
Your Singer Model 127 with the Sphinx decals is very easy to service yourself. You don't need to pay to get it done just follow the manual on where to oil the machine. Take off the needle plate and clean the feed dogs - make sure there is no thread caught in there too. I hope you have the manual? If not you can download one free from the Singer site. That machine will sew through several layers of jeans without a problem. Just oil her up and start practicing learning how to treadle! Have fun!
Does anyone know of a place where you can get parts for treadles and such machines? Information above was helpful but I want more information.
Lovely machine, most definitely a 127, lucky you!
If you go to my blog and Youtube channel - links below - you will find loads of information to help you. You should be able to get your machine up and running in no time. If you aren't used to treadling, try a strip quilt first, and you will soon have something to show on the thread "Quilts made using vintage machines."
