Gander, game and skinned geese (kilo) brought round (4-3)
I believe the answer is:
look-see
'gander' is the definition.
(I've seen this before)
'game and skinned geese kilo brought round' is the wordplay.
'game' becomes 'loo' (historical card game).
'and' says to put letters next to each other.
'skinned' means to look at the middle letters.
'kilo' becomes 'k' (phonetic alphabet: alpha, bravo, charlie etc.).
'brought round' is a reversal indicator.
The centre of 'geese' is 'ees'.
'ees'+'k'='eesk'
'eesk' backwards is 'ksee'.
'loo'+'ksee'='LOOK-SEE'
(Other definitions for look-see that I've seen before include "Young's - relates stress and strain (Physics)" , "Inspection (colloq.)" , "Dekko" , "Brief inspection" , "Survey, inspection" .)
