Another unidentified 428 Frua convertible at AC Heritage...

[SunDude]

I guess I'm a glutton for punishment, but here goes again...

I came across these webfind photos of an unidentified 428 Frua convertible at AC Heritage/Brooklands Cars Ltd. in June 2021. The car is RHD, blue with black interior, with blacked-out wire wheels. It doesn't match any of the cars in my files, so I would appreciate some help identifying its chassis number. My best guess is CF11, one of the "missing" 428s.
