Parts of helmets made from thin scraps? (10)
I believe the answer is:
'parts of helmets' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'from thin scraps?' is the wordplay.
'from' indicates anagramming the letters (the anagram comes from the same letters).
'thinscraps' with letters rearranged gives 'CHINSTRAPS'.
'made' is the link.
Can you help me to learn more?
(Another definition for chinstraps that I've seen is " that keep helmets on".)
