That isn't about lost pictures. It is discussing the lost film footage (the high quality originals anyway).
That may have been found.
In any case it isn't any sort of support for what you claimed.
...took their designs with them, all drawings and documentation was lost, everything.
This is the same assertion again. Again, what support do you have for this?
An aside: What is pointed out below is obviously correct. I wouldn't attempt to take a '60's vintage F1 design to Monaco next season and expect to do very well at all, would I?
I am sort of surprised that after the last few weeks you would continue to make statements that have no support and are very probably wrong. You have both a deficient BS detector and a limited ability to learn from past mistakes.
(aside from the fact that is it against the rules now).
