Thanks for your interest in this project, senseispcc- but it has become unnecessary and I have abandoned it. The reason I started it (while trying to learn GIMP from scratch!) was to produce some skins for the VVS P-39's in the Kuban early 1943 era- especially the 45th IAP.
FoxbatRU recently released a FANTASTIC skinpack of 45th IAP & 16th GIAP Airacobras from this era of fighting in the Kuban 1943 that cover these 2 particular aircraft- and several more. If I could have placed a special order for a skin pack- it would be the one he created! I really appreciate his efforts- and the results are much more aesthetically pleasing than the results I was getting!!! I am indebted to him- and highly encourage folks to get a hold of his collection of skins in this thread (and the Russian language forum as well):
I would also like to highly recommend the book "Attack of the Airacobras: Soviet Aces, American P-39s, and the Air War Against Germany" by Dmitriy Loza (a Sherman tank commander for the USSR during WW2, and historian) Translated and edited by James F. Gebhardt. It has a lot of great anecdotes and excellent information on the P-39 units: the evolution of tactics, technical issues with the P-39 and how the VVS addressed them, airfield set-ups, mission types, interesting pilots, etc. It covers the way P-39 operations evolved from late 1942 and operations in the Spring of 1943 in the Kuban through the fall of Berlin in 1945.
Thank you again to FoxbatRU for his tremendous skinpack!
