No special needle for mine, a regular 15x1 works in the Family Rotary.
Looking around on parts supply sites, it seems that this type of bobbin and case works in several different vintage machines, including White, Kenmore, Franklin, Domestic, and Viking. In the pictures, the case is original to my machine, but the bobbin is new from Sew Classic.
