Does anyone who know the source about luftwaffe claimed 77,000 kills on eastern front?

[gomwolf]

I read some claims on web which suggest 'luftwaffe claimed 77,000 kills on eastern front' and I couldn't find any source about it. Only document I found from keyword "77,000" and "luftwaffe" was a book written by Andrew Brookes. He claimed "luftwaffe 'lost'(not claimed) 77,000 aircrafts in eastern front" and this claim also have no source. According to Claus Christian Szejnmann, it is unreferenced claim. I found source. Ivan Timokhovich claimed this at 1976 at his book.

So... Does anyone who have more information about it? If you have, please release the information! And also if you have total victory claims of luftwaffe by front with source, please release it, too!

I had tony wood's documents but someone said it is not complete claim list. So... I'm still finding more...
