Narrative:

Practicing landings (touch 'n goes) I was on a long final (due to practicing no-flaps approach and landing) to runway 23 at cbe. I was about 1/3 to 1/2 mile from runway threshold and about 150 feet right of extended centerline. I happened to see an aircraft (I believe a small cessna) about 200 feet below me and about 150 feet to my left.I initiated a go-around; and announced I was going around on unicom. Someone (presumably the pilot of that aircraft) said 'sorry about that - I was on the wrong frequency'; or something very close to that. I replied something to the effect of 'no problem; no one got hurt'.I did a couple more landings after the incident and put the aircraft away. I did not see the other aircraft or pilot.at no time did I hear the pilot of that aircraft on the radio; except immediately after I announced that I was going around. I do not know if he had flown a partial or complete pattern or did a straight-in approach.preventive action to try to prevent this from happening again: 1) try to improve my scan for other aircraft. I was looking for other aircraft; but just did not see him.2) make sure I am on correct frequency; monitor radio traffic to build situational awareness; and clearly announce my position/intentions as we're supposed to do.
