Narrative:

I am a little fuzzy on the details as this happened earlier this year and I did not think to report it until I read a recent article reminding me of the NASA system.I approached the airport from the west and announced my altitude and that I was going to overfly the airport midfield at 1;500 feet. I announced on CTAF when I was over midfield. I announced again when I turned right downwind for xx which is the pattern for xx. I was announcing my downwind to base turn when I started and looked right and there was a 'warbird' type plane that was at my pattern altitude opposite direction just off my wing. He was way too close. I straightened out then announced again and made my base turn. I announced turning final and then once again at a 1 mile final. As I scanned the runway on short final I [saw] the warbird again on the runway. He exited the runway just in time for me to land prior to going around.during this whole ordeal there was never one radio call from the warbird pilot. I was not on with center for following as this [was] a local flight and at that altitude I would not be able to pick them up anyway. Contributing factors could be that it was a calm wind day and even though [the chart supplement] states that xx is the calm wind runway; the pilot may have thought he could just pick the one he wanted. It is right pattern for xx and left pattern for [the opposite runway] which puts both downwinds on the same side at the same altitude. I don't know why that is. Seems dangerous; especially with no terrain or residential area as a limiting factor. I just thought I would share this event.
