Procedure; Human Factors
I was on about a 3 mile final approach to runway 34; inside the Class D. A [warbird] was instructed to follow me and report me in sight. Evidently; the tower assumed that [the warbird] was a Cessna 172. The [warbird] came within 100 yards horizontally and less than 30 ft. vertically (as told to me by the pilot afterwards) before he saw me and took evasive action and did a left 360.
SR22 pilot reported an NMAC on final to RNT airport with a warbird.
