I have been an overly enthusiastic member for about 30 years, never owned anything with a genuine S/N. BUT, my FFR Replica is well known, track car, at many conventions. I happily acknowledge it as what it is, a replica, track car, fun car. Yes, I do get lots of sneers from the CSX boys, all of them. BUT, I have more fun than most of them, so it's even.
Enjoy the car, build it for you, have fun, be a good and active member of the club.
