Revolver taken in hand by driver (5)
I believe the answer is:
This might be a double definition.
'revolver' is the first definition.
'driver' is the second definition.
'taken in hand by' acts as a link.
This may not be correct. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for wheel that I've seen before include "Turn round quickly", "Circular steering device", "Turn on axis", "Gyrate", "Roller on vehicle".)
