Odd people say this about pattern parts, when a lot of the time they are done on the same presses that have been sold on.
It is not financially viable for someone to make the die etc for stamping out pattern wings for a ever decreasing market so they buy the oe old ones, true they are a bit worn from all the pressings.
I bought two new Hadrian wings for mine and the fit was 100% perfect, no better no worse than new genuine ones, the guy who did the work, works for Norwich Union as a repair estimator and it was his recommendation of make.
I also used thier front slam panel, bonnet, cross member, etc etc, all was ok, apart from the bonnet the interior frame bit was not bonded to the skin!
