Welcome!
You really did great! I think you have a Singer model 127 due to the boss for the motor mount. Most machines with the Sphinx decals are pretty beat up. Your looks like it's in great shape. It uses standard sewing machine needles and long bobbins are still available new as well. Try treadling it. You might be surprised at how easy and enjoyable it is.
And what Steve said. Read the stickies on cleaning your machine and watch Muv's videos. Use only sewing machine oil. Other oils can cause problems down the road.
You can download a free manual at Singerco.com.
