Tisch, I had to buy a universal bobbin case for a 1970s Montgomery Wards that came without one. It also fits a Admiral from the 40s and probably a Necchi from the same era and my 15 clone. There are basically only two types - I needed the one with the finger straight up. Check at sew-classic.com I was able to get at my local LQS for the same price with no shipping and easy returns. The brand doesn't matter - the quality and fit does.
