I'm in the same boat... I used to spend small fortunes trying to re-unite groups, bars, even photo albums that had been torn apart (would you believe I had to pay an immense bribe to a German seller who had been tearing photos out of an Imperial Aviation album that included original photos featured in a number of books!! Eventually, with much expense and heartache, I was able to salvage most of the album, including the pages he had ripped and cut photos from, destroying the pilot's hand-written notes in the process.... The truly sad part was later on (and this IS what usually happens) not one other person cared!
