Does anyone know what kind of camera a Quantaray lens would go to?

I found a Quantaray Lens no.143236 with a 75-200mm zoom while cleaning out a closet at my grandparent's house. I tried fitting it into my Cannon EOS Rebel XS, but it was too small. Does anyone know what kind of camera it would fit? It is obviously very old, heavy, and is no longer made.
