Trunk of Lincoln had chromium plating (5)
I believe the answer is:
caber
'trunk' is the definition.
(I've seen this before)
'lincoln had chromium plating' is the wordplay.
I cannot really understand how this works, but
'lincoln' could be 'abe' and 'abe' is present in the answer.
'chromium' could be 'cr' (chemical symbol) and 'cr' is found in the remaining letters.
No letters remain.
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 caber that I've seen before include "What's tossed" , "Pole needed for game up north" , "Scotsmen throw it in sport" , "It's tossed in Scotland" , "requirement for Highland fling?" .)
