Traded timber for an old model car! (5)
I believe the answer is:
dealt
'traded' is the definition.
(I've seen this before)
'timber for an old model car' is the wordplay.
'timber' becomes 'deal' (deal is a kind of timber).
'for' means one lot of letters go next to another.
'an old model car' becomes 't' (I can't justify this - if you can you should believe this answer much more).
'deal'+'t'='DEALT'
Can you help me to learn more?
(Other definitions for dealt that I've seen before include "Gave out playing cards" , "Dispensed (cards)" , "Traded" , "Handed out (cards)" , "Delta (anag.)" .)
