The P-40 line deserves a facelift/remodel as much as any plane that served with British in North Africa, the Soviets in the east, & the US, Australian, and New Zealand forces in the South and Southwest Pacific.
Hard pressed to call the contributions the P-40 made in general as "minor".
According to America's Hundred thousand if you count all the variants of the N (-1 through -40) model P-40 over 5200 were produced. The N-1 was first delivered in March 1943 and the N-40 was delivered in October 1944. The first victory for the type was scored by the RAF in Libya on 6/8/41 and it was flown by allied forces through 1945, the last entry in the time line here says that the RAAF bombed it's final targets in Borneo on 7/23/45.
