Wild West gunfighter's haul: a muffler? (7)
I believe the answer is:
earplug
'a muffler?' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I don't see?
'wild west gunfighter's haul' is the wordplay.
'wild west gunfighter' becomes 'earp' (I've seen this in another clue).
'haul' becomes 'lug' (I've seen this before).
'earp'+'lug'='EARPLUG'
Can you help me to learn more?
(Other definitions for earplug that I've seen before include "affording protection for organ" , "Device to keep out noise" , "Hearing protector" , "Lug stopper?" , "Noise protector" .)
