[Franek Grabowski]

I am awared of a case of certain pilot(s), who filed no claims after dog fight, but were asked to do so, after receiving a report, that some German aircraft were shot down at the time and place. Having done so, they were credited with victories, but nobody realised those ground witness reports were not confirmed to say the least! Who is an overclaimer then?
That said, there is another issue of accuracy and availability of the other side's records. While it is perfectly possible to asses, say RAF losses during fighter offensive, try to tell anything about Italian losses during Tunisian Campaign. I cannot say anything about Japanese records of units fighting AVG, but I know they are scarce for 1943.
