Going back into this, I spent some time on a phone call with Mid Beckett trying to establish which chassis that was for my records. He stated unequivocally that it was not a Buckler chassis at all, but a copy as he could not get a "real" one, and much easier to register as a Buckler than dream up another name.
That does not mean that your car Paul is in the same situation. Vic's wife told me that he gave it another name, it's now recognised by the folk who like Bucklers as such, a Buckler. Some were "authorised" copies by Buckler NZ, some were just done by those who could either not afford them, or Buckler NZ could not deliver, so they built anyway. I know of a car that was in exactly that cae, 2 cousins bought one rolling chassis, built another chassis and some of the parts supplied went onto both cars.
