Carriage German mayor ordered originally turned up (6)
I believe the answer is:
hansom
'carriage' is the definition.
(hansom is a kind of carriage)
'german mayor ordered originally turned up' is the wordplay.
'german' becomes 'hans' (I've seen this before**).
'originally' suggests taking the first letters.
'turned up' shows that the letters should be reversed in order.
The initial letters of 'mayor ordered' is 'mo'.
'mo' backwards is 'om'.
'hans'+'om'='HANSOM'
(Other definitions for hansom that I've seen before include "Two-wheeled one-horse carriage" , "Old horse cab sounds attractive" , "Victorian cab" , "Type of cab" , "One-horse cab" .)
