There were inconsistencies in the original publications about the Sutton Hoo finds. I recall that the number of bowls that had been discovered changed from report to report. More significant, perhaps, was how certain objects were described. What exactly is a 'sceptre', say?
And then there's the helmet. Look very closely and you realise how little of it remains. I was at the British Museum once and a guide stopped in front of it and announced to his party, 'There is a poem written about this. It's called Beowulf.'
