I want to know the answer to the following question:
Who reworked the Royal Institute's medal desgin in 1931?
All the background I'm provided with is that "The design of the Institute's Mycenean lions medal and the motto ‘Usui civium, decori urbium' has been attributed to Thomas Leverton Donaldson, who had been honorary secretary until 1839.". Is that enough to answer the question?
Answer: no
