Lost ww2 medal - trying to track down Cornelious Moore

hi i am trying to track down a medal thet belonged to my grandpa. Unfortionately i dont have alot of helpful information on him.

he served in the REME,
came from scotland,
name was Cornelious Moore,
dob - 14/10/12,
was captured at the begining of the war and was a Japaneese prisoner of war,
he was awarded a medal (for bravery i believe - not 100% sure it was definetly for bravery) but he refused to accept it as he believed the there should not have been a war.

i am trying to track it down for my dad. any information anyone has would be greatly appreciated. even any web sites or phone numbers i could try. really want to track it down.

thanks Amanda x
