I was on 617 when it reformed in '58 and quite naturally the
dams raid' was a popular topic. Pictures before and after the raid were everywhere to be seen.
When the Queen Mum paid a visit to present Colours to the Sqdn
a very large mock-up of the Mohne dam was constructed in the hangar. A model Lancaster then came flying over, suspended on wire, there was a very small explosion, and the dam collapsed. As an aside, prior to the QM'S visit the protocol chaps were most anxious about the small explosion, apparently there is a strict limit to how large an explosion can be in the vicinity of Royalty.
I've mentioned this before but on a trip to Nellis in '59 we were hailed as the 'dambuster boys' by the Las Vegas press. Everyone was rather embarrassed.
two graves for Nigger at Scampton; one outside the hangar,
I'm pretty certain Nigger's grave was on the left as one came out the side door of the hangar, on the airfield side.
It was said that crews often peed on the grave for good luck!
