1924 Empire Exhibition medal - incorrect composition - please remove [решено]

Hi,

Could this medal  https://en.numista.com/482892 be removed please? 

It was not issued in silvered bronze.

The original source for this entry was the British Museum: 

https://www.britishmuseum.org/collection/object/C_1924-1001-18

Source clearly states composition is bronze, and we have an entry for that composition: 

N#556445
 

Also letter from Royal Mint states only issued in silver and bronze:

Thanks 

Simon

Thank you for the research!
