I believe the aircraft you're referring to is the PV-2 15-1473/BuNo.37507, previously registered as N86492 (and N6643D). It has been sitting (in different locations) at Falcon Field for many years. There was some work done back in the 90's to convert the nose of the aircraft to make it resemble a Ventura (together with the RAF paint scheme).
Here are a few more recent photos of the aircraft:
