Narrative:

Aircraft reporting on right base, then on final for runway 26L, at which time I had similar type aircraft on final for runway 26L -- which I believed was P28A (aircraft involved). The end result is that the P28A was cleared to land at poc runway 26L and aircraft was at ont, which is 9 mi east of poc with the same runway confign.
