Narrative:

After reporting 10 miles out from okv on the ILS 32 over the CTAF I learned there was one airplane ahead of me on the ILS 32. I established visual with the prior airplane which was 5+ miles ahead and no factor. Shortly after this a third airplane reported as a commander called 6 miles out from okv on the ILS 32 approach. The reported position at the time put the commander behind me by approximately 2 miles. No communication was ever established with the commander. When I was 3 miles out from okv established on the ILS 32 approach the commander reported 4 miles out. Again I inquired if the commander had traffic ahead of them in sight. Again; there was no reply. Immediately after this the traffic ahead of me landed and advised they would need to roll to the end of the runway due to spongy brakes. I was still looking for the airplane trailing me (the commander) and lifted my right wing and saw the commander at my 5 o'clock position just 30-40 ft away and 10-15 ft above. I immediately turned left; descended and reduced power. No contact was ever established with the commander. They must have seen my evasive maneuvering; because they turned the opposite direction and left the area.I had in continuous operation all 3 navigation position lights; red anti-collision beacon; wingtip mounted white anti-collision strobes and led landing light. Post flight checks verified all external lights were operational. In my opinion there is no reason the commander airplane could not see my airplane unless they were simply not looking for me. Communication was never established with the commander airplane and I find it highly doubtful that any communications with them were blocked due to the airplane ahead that had landed before my airplane.I recommend the FAA stress proper traffic scanning and responsibility more so than it does now. I also recommend minimum volume level specifications for aircraft radios so communications radios can never be turned down so low that a person could not at least hear a whisper over a communications radio a test minimum that all pilots with medical certificates must be able to pass.

Title: A C150 pilot suffered an NMAC with an overtaking 'Commander' aircraft when both were on final approach to a non towered airport. Although the 'Commander' pilot made position report he never responded to transmissions from the reporter who became concerned as their respective distances out on the ILS got closer and closer.
