Hi -- pls don't use WD-40, it is too strong.
Ask Manicmike for the name of something like Tri-flow, available at bike shops. Beyond that, plain old Sewing Machine Oil is the preferred lubricant AND cleaning solution, inside and out, for the black cast iron machines like yours.
I was curious about the lever seen towards the top of this photo.

(Below it is the bobbin winder.) If you have time, I would n't mind seeing that lever from a different angle, like 3/4 looking towards the front so we can determine what it is meant for. I haven't seen anything like it before, but that of course doesn't mean anything :-) .
Getting the needle to move is usually surprisingly easy and the best part of fixing up old sewing machines -- making it useful again after it has lain dormant for 50 or so years, even if we don't use it at all or not much...
All it takes usually is oil in all the right places, where metal meets metal and should be moving...
