Old Toyota Sewing Machine (Seal TN15)

Lovely Old Toyota Sewing Machine with 30 different stitch cartridges. Not currently in working order. I've cleaned and oiled it recently, but the needle won't move on it's own. When you push down on the peddle you can hear the motor, so I think perhaps it needs a new belt? I'm not a sewing machine repair person, so I have no idea.
