montgomery signature URR988

I recently saw this machine at Value Village. It looks decent, but
possibly missing some parts (no accessories, but not sure if it comes
with them) and the manual. Does anyone have experience with this
machine, finding parts, maintenance, enjoys using it?

Any advice/input is much appreciated! I am a beginner sewer and
thought this machine is a fit--simple, sturdy, all metal--as long as I
can replace what's missing. Thanks!
