Where Do You Get A Manual For An "Electro Grand" Sewing Machine? I Need To Oil The Parts So It Can Be Used. Also, Is There Another Name Brand That Is Built The Same Way?

I have my grandmother's Electo Grand. I think she bought it around 1965. I do not have a manual either. Her cousin sold it to her in KY. He has since passed, but one time I told him I could not find the manual and the machine needed oiled. He told me to oil everything that moves. I did and it works great!
