Thank you, Leon for posting how to post pictures. I agree that this machine would have been made by National.
Welcome to QB, Anderson78. There was recently another Wards machine that has the leaf tension. While it is a different machine, there are some links that may help.

my post #2 regarding the needles for that machine would apply to yours as well. I don't know if Jon has any needles, but he is the one to see if he has any 20x1 needles. There are several ways to contact him as he has several places on the web.

There is a video at
https://www.youtube.com/watch?v=Kf4EdcMx0eE It is not the same machine, but is similar as to the threading of your machine. There should be a notch on the back side of the screw and you want to pass the thread behind the screw through the notch to the underside so that it goes between the two springs and then as seen in the video. The piece on the faceplate is in a different location but is threaded the similarly.
As for winding the bobbin, it is quite similar to the instructions for the Burdick as seen at
https://www.sil.si.edu/DigitalCollec...ges/image6.htm You will want to bring the thread behind the bobbin winder and through the notches/thread guides as shown.
As far as cleaning and refurbishing the cabinet, see
my post that I referred to earlier.
Looking forward to seeing your machine and the things you make with it.
