Narrative:

We were flying a visual approach to runway 33 at fnl; established on final and using the ILS for guidance. We had made 2 or 3 calls on unicom while on final advising traffic of our pros and intention to land. Earlier on final; we heard a plane call 'base;' but did not see him. Quite awhile later (2 or 3 mins) the same plane was turning final and descending on top of us in our 11:30 O'clock position. We initiated a right turn and missed approach with no further incident.
