According to the literature linked to their showing at Salon Prive, there are three Fighters left to build.
That number seem to have varied over the years, as other people seem to have been involved, and I met with a chap a few years back who claimed to have bought the last of the continuation Fighters… so who knows!
I’ve seen the black car in the metal, alongside the burgundy one, and whilst the finish is fine, it still looks ungainly to my eyes.
