Speculator’s vision producing gold? (5-3)
I believe the answer is:
bulls-eye
'gold?' is the definition.
(I've seen this before)
'speculator's vision' is the wordplay.
'speculator's' becomes 'bull's' (I've seen this in other clues).
'vision' becomes 'eye' (I've seen this in another clue).
'bulls'+'eye'='BULLS-EYE'
'producing' acts as a link.
(Other definitions for bulls-eye that I've seen before include "Sucker" , "Centre of the target (4'1,3)" , "Middle of target" , "Light - gold - sweet" , "Accurate shot" .)
