An old-fashioned copper (6)
I believe the answer is:
peeler
This might be a double definition.
'an old-fashioned' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'copper' is the second definition.
(I know that copper can be written as peeler)
Can you help me to learn more?
(Other definitions for peeler that I've seen before include "kitchen utensil" , "Kitchen gadget - old policeman" , "Old copper" , "Old policeman (useful for potatoes!)" , "Old London policeman" .)
