In the words of the immortal Count Basie, "One 'mo time!"
I'll dig up my files, but Brian Angliss wrote a letter to CS after his "continuation" series was announced. He stated that ALL Cobra chassis/bodies were manufactured by AC Cars and that EACH unit was assigned a serial number. AC manufactured no imcomplete chassis/body units, all that were manufactured had been accounted for.
I also have a letter signed jointly by Angliss and CS were CS admits that his continuation cars were/are of U.S.A. origin with no parts manufactured or supplied by AC.
Give me some time, and I'll post them again.
By the way, it doesn't help when experts like Brock Yates and Alain deCadenet don't know the difference between a CSX4000, an original and a continuation car. Did anybody catch deCadenet's discription of a CSX4000 at the Barrett-Jackson auction? He said the car was an almost perfect duplicate and that the only difference between it and an original Cobra was the hood latches. He claimed he could tell it was a 4000 because they faced a diffrent direction. I think they were unlatched!
