Hi,
Thanks for all the replies. I'll try and locate a copy of the book mentioned by Frank.
At the moment I'll stick with Allied pilots only.
Found a good link for Charles Curnow Scherf. He used to go 'on holiday' to 418 Sqn, his previous unit, and carry out lone sorties. He achieved more kills during these 'holidays' than he did while he served with the squadron.

Excellent stuff indeed.
