I just caught up with this. Very nice work indeed, @johnb. Good work on the decals.
It's interesting to discover - through Sir Max Hastings - that Guy Gibson was the polar opposite to the "official" portrayal in Paul Brickhill's book and Richard Todd's portrayal in the movie The Dam Busters. Sir Max recently published "Operation Chastise", the book he's worked on forever - he was able to interview every living participant back in the 1970s, including Barnes Wallis and Sir Ralph Cochrane, but most particularly the crews. I had seen something of the real attitudes toward Gibson in the show "secrets of the dead" where one of the crewmen called Gibson "a right little English schoolboy," and he didn't mean it as a compliment. Johnny Johnson wrote in "Wing Leader" about meeting Gibson one night in an officers club and came right out and said he was not a nice guy. What I as a writer find fascinating is that a guy with the high personal negatives Gibson had could attract people like Hopgood and Mickey Martin and the rest of the "legends" - who were already legends and no one would have said a thing if they'd taken a pass on volunteering for 617. That's why I really wish Peter Jackson had made his movie, because the screenplay Stephen Fry wrote was as far from the "official story" and as close to the truth as anyone was ever going to get.
I really can't recommend Sir Max's book highly enough; the truth is always more interesting than the Official Mythology.
