Instrument of fraud sure to see American sent down? (10)
I believe the answer is:
concertina
'instrument' is the definition.
(concertina is a kind of instrument)
'fraud sure to see american sent down?' is the wordplay.
I cannot really understand how this works, but
'fraud' could be 'con' (con is a kind of fraud) and 'con' is located in the answer.
'see' could be 'c' (the word for the letter, according to Chambers) and 'c' is found within the answer.
'american' could be 'a' (common abbreviation - e.g. in organisation names) and 'a' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for concertina that I've seen before include "fold" , "gig belonging to American" , "Squeeze box" , "Instrument played like an accordion" , "Musical instrument with bellows" .)
