Narrative:

As we now have many versions of A320 family aircraft; many are not equipped with ADF or a second weather radar system. I am finding that most but not all of these aircraft do not have deactivate / inop placards on the system 2 radar selector panel or EFIS control panel ADF selector switches. Some aircraft have them while many do not. Are they required? If so; is this an aml entry item or something that maintenance is able to get to as the aircraft cycles through scheduled maintenance? Read file; OM guidance or release sel [selected equipment list] information regarding not installed cockpit equipment/placarding requirements.
