September 29, 1943: pilot J/Lt. I.I. Mikailov anxiously scanned the Russian tundra below for familiar landmarks. He had just survived a battle with four JGS Bf 109s, but as the fuel gauge edged toward empty, it was obvious he was still going to lose his aircraft. Resigned to his fate, he bellied his P-40 into the soft turf, and the war was over for Curtiss Warhawk 42-10256. Mikailov was unscathed, but 10256 would sit for another 50 years before its badly brutalized remains would be rescued.
P-40 42-10256 was a "K" model, which was a continuation of the P-40E line but with the more powerful Allison V-1710-73(F4R) engine installed. The bigger engine required more vertical tail authority, so the initial production batches used the short fuselage of the "E" models with additional vertical tail area in the form of a fin fillet. Later, the horizontal tail was held at the original length, but the rudder and fin were moved back nearly two feet as they were on the "F" models
When 42-10256 was recovered, it was barely above junk status. A bomb blast had removed any trace of fuselage from behind the canopy, and locals had hacked off everything that could be removed. When the remains hit Ken Hake's facility in Tipton, Kansas, he stripped it down to its primary structure and began to build a new airplane around the bones. Then Fagen Fighters, owned by Ron Fagen in Granite Falls, Minnesota, bought the airframe and continued the process. Erik Hokuf completed the restoration; it was his first attempt at such a monumental undertaking
