Colour B o B footage shown on news some years ago

Many years ago i remember the local Anglia or BBC T/V news equivilant showing some colour footage [i believe it was the only surviving colour footage of the B o B ].
I think it had been discovered as it had been hidden away incase the person taking it was accused of spying during the war.
Does anyone remember this or know of it. 🙂

Quick edit ,did an online search and found this regarding the FAA not the same i know but thought it may interest someone . http://www.fleetairarmarchive.net/Multimedia/Index.html
