Pedlar (6)
I believe the answer is:
hawker
'pedlar' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for hawker that I've seen before include "He sells from door-to-door" , "Street-seller" , "Person who carries goods about for sale" , "Falconer; salesman" , "Travelling street trader" .)
