I believe that Guy Gibson's last op in Lancasters was on 19 Jul 1944 when he wrangled an Op with 630 Squadron although officially he was non-operational at the time. I once had the published facsimile copy of Gibson's log book done by "After the Battle" in the early 1980's but foolishly loaned it to somebody and have never been able to get it back. I am keen to have a scan of that one page, please can anybody help ?
