Terrible machine! Send it to me now before it contaminates your whole house.
Oh , you won't do that do that?
Several thing to tell you. The id plate is under the machine, at the edge of the bottom cover that is held on by a thumb screw. That will date it for you.
You have the bobbin case. Huzzah, and it is placed correctly. YAY.. Oil it more than the manual says. It has been dormant for decades. oil all the steel parts that rub against steel. Disconnect the belt and turn it while you are oiling it. Unplugged.
The bobbin area and just behind the bobbin are trouble points for this machine. Tiny bits of thread can get in there and lock up or create a lot of drag.
Thread it and power it by hand and you can see if it will sew.
