Makings of a model young fox (3)
I believe the answer is:
kit
This might be a double definition.
'makings of a model' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'young fox' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for kit that I've seen before include "Old song 'Pack up your troubles in your old . . . bag'" , "Set of parts sold to be assembled" , "Football top, shorts, stockings and boots?" , "Outfit" , "Necessary equipment" .)
