Welcome!
Pretty machine! I don't know the make, others here will. Spend some time playing in here:

Also, Glenn has a couple good tutorials on restoring the finishes on these old machines too:

Use sewing machine oil or Tri-Flo (a light synthetic oil) only unless following Glenn's or Muv's instructions otherwise. Sewing Machine oil is safe on any finish and won't gum up the works like other oils can. You can start by oiling everything that moves or looks like it should move, then do the hard part: Walk away for a couple days.
That will give the oil a chance to soak in and work it's magic, making things easier later.
Once you know what you have, there may be more info at ISMACS or needlebar.org too.
Please keep us posted on your progress,
Rodney
