Storage compartment for draughtsman (6)
I believe the answer is:
drawer
This clue is a double definition.
'storage compartment' is the first definition.
(I've seen this before)
'draughtsman' is the second definition.
(someone who draws)
'for' acts as a link.
(Other definitions for drawer that I've seen before include "Sliding box in chest" , "Cheque signatory" , "One taking out money" , "Part of bureau" , "Box in chest - one sketching?" .)
