Trade in lead production (4)

Ross

I believe the answer is:

'trade in' is the definition.

'lead production' is the wordplay.
'production' indicates an anagram.
'lead' is an anagram of 'DEAL'.

(Other definitions for deal that I've seen before include "Buy and sell", "Distribute playing cards", "split deck", "Large quantity (of wood?)", "What business folk do".)

I've seen this clue in Mirror.
