Two Englishmen down under making a gun (3-3)
I believe the answer is:
pom-pom
'a gun' is the definition.
(I've seen this before)
'two englishmen' is the wordplay.
'two englishmen' can mean two substitutions for 'englishman'.
'englishman' becomes 'pom' (pom is an Australian term for an English person).
'englishman' becomes 'pom' (pom is an Australian term for an English person).
'pom'+'pom'='POM-POM'
'down under making' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for pom-pom that I've seen before include "Decorative woolly ball" , "Woollen clothing ornament" , "Decorative tuft on shoes etc." , "Fluffy ball - type of gun" , "Variety of dahlia" .)
