Spit Mk IX at Boca?

Steve Moore caught site of an interesting aircraft project at the airport in Boca Raton FL. Relying on Ross Sharp we note the radiator is under the port wing (Mk IX or later) and the rounded vertical stabilizer (Mk V modified to Mk IX)—so it appears that the plans for the aircraft, if it is a replica, are those of an early Mk IX—or another mark. A beautiful aircraft at a local airport—how nice. Thanks to Steve for the news and the images of this intriguing project.
