Also would help to know the initials on the second image.
HN
HV
HW
Could be any of those.
Henri Éduard Navarre (1885 - 1971) France
Hermann Noack II (1895 - 1958) Germany
Heinrich Waderé (1865 - 1950) Germany
Those are some known medallists around at 1932 date.
Cannot find a picture of what their initials look like on their work.
Still could still be someone else though.
