Amy wears the collar number 995, the number she wore in the Metropolitan Police. Numbers do not follow an officer who transfers to another force, so Amy should have had a different one.
Amy, Sgt Allan, and others wear three-figure collar numbers. All West Yorkshire Police uniformed sergeants and constables wear four-figure numbers (mine was 8386).
The cap badge is shown as the common EiiR type. The West Yorkshire badge is different, and shows the arms of the City of Wakefield.
