Hi guys
Here is an interesting thread that I came across on a Russian language forum concerning claims and losses of the Luftwaffe and VVS over East Prussia in 1944. I have no idea how accurate the information posted is (perhaps the various Russian contributors can inform us) but I hope this is useful and helpful.
