Hartmann: claims vs. victories

[zakarpatska]

I have a quick question about the claims/losses. If I've understood correctly Hartmann's claims here are related to the losses of the type of aircraft Hartmann claimed. Is it possible that there are situations where Hartmann identified the type of aircraft incorrectly and that there is a corresponding loss, but of a different type of aircraft?

I apologize if I have missed something, or if this has been addressed somewhere else. I'm just trying to understand the information presented.

On a side note I am interested in Red Air Force operations. Are there any good references in English/German on the Red Air Force? Sadly, I don't read Russian.
