Recently I acquired a Simplex toy typewriter from about the late 1920s or early 1930s. In it there was some paper with the name of Charles I.Kroh, of course the proud owner of the toy. Also the names of a Donald and Robert Kroh were mentioned. A possible address: 114 or 144 Pott.(?) Can anyone identify this Charles I.Kroh ? Maybe it could give my typewriter a date.
