Untanned pelt (7)
I believe the answer is:
rawhide
'untanned pelt' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rawhide that I've seen before include "Untanned animal skin cut to make whips and ropes" , "Whip" , "Stiff untanned leather" , "Leather before tanning" .)
