Pirate getting bit of a shock maybe finding gun (9)
I believe the answer is:
flintlock
'finding gun' is the definition.
'flintlock' can be an answer for 'gun' (flintlock is a kind of gun). I'm not certain of the 'finding' bit.
'pirate getting bit of a shock' is the wordplay.
'pirate' becomes 'flint' (Captain Flint from Treasure Island).
'getting' says to put letters next to each other.
'bit of a shock' becomes 'lock' (shock can mean a mass of hair).
'flint'+'lock'='FLINTLOCK'
'maybe' is the link.
Can you help me to learn more?
(Other definitions for flintlock that I've seen before include "arm" , "Weapon" , "Type of firearm" , "one was fired" , "gun" .)
