Very fine specimen (6)
I believe the answer is:
beauty
'very fine specimen' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for beauty that I've seen before include "Stunner" , "Period when power supply is unavailable" , "Camberwell - (butterfly)" , "` `. . . . . . is only skin-deep' '" , "Good looks" .)
