Buccaneer's internal recce pack

Hi,

I have a very specific question, I hope you can help me. As most of you probably know, the Buccaneer could carry an recce pack in its internal rotating bomb bay. I want to know something about its function: I assume that the bomb bay has to rotate out before the recce pack can be used (since the bomb bay doors have no windows for the cameras). Is that correct or was it used in another way?????
Also, I read that the recce pack was only used on RN Buccs and not on RAF and SAAF Buccs. Can anyone confirm that???
Any pictures (especially detailed ones) on the Bucc’s recce pack will be much appreciated!

Best regards,

Ference.
