Not good I'm afraid on blowup, the original is in the loft with hundreds of others! I do believe the Canberras were on their way back to the UK, I seem to recall a white Canberra from Upwood/Boscombe flying thro' mushroom clouds, I have a piccy of that somewhere too.
Les Bywaters is the Canberra man, I'll see if I can get him to post a reply.
