Part 1. the BoB
John Alcorn's "Top guns of the BoB" article
Looks like very well compiled data, and he put a lot of work into it, starting in 1970.
Ok, some conclusions.
Period: July to and with October, so 4 months (AFAIK)
LW battle related losses:
1.609
To RAF fighters:
Between 1197 and 1231
Top scoring sqn is 603 with 57 kills, there off 47 109's.
(based on LW losses, not RAF claims)
Actually, the Hurricane equipped 501 has 40 kills, there off 30 109's!
