Yep, I knew there some FW190 replica's out there. As Jason points out, its been a long standing argument, especially in vintage racing circles, what's authentic, and what's a replica. I remember a big stink being raised about a Lancia D50 being entered for some historic events, however the only original components were a engine, and perhaps some drivetrain bits.
I suppose I'm a bit of a purist when it comes to historic warbirds. That said, most vintage WWII aircraft still flying have gone through such extensive rebuilds there's very little original left on them. Most of them were built assuming their life expectancy would be around three weeks or so.
