Mortar carrier (3)
I believe the answer is:
hod
'mortar carrier' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hod that I've seen before include "Pole used to carry bricks" , "Bricklaver's carrier of orthodox kind" , "Coal-scuttle" , "Brick-layer's tool" , "Open trough for carrying bricks" .)
