Ah, Greg Herrick's trimotors! He has had a few Fords in his collection, not sure, but I think he still has 4AT#10, the oldest Ford still around. It has the rear sloped windshield of the very early 4ATs, and the one modeled in Revell's 1/77nd release from the last century!
Can't wait to see the Stinson build! Now, if only I could find a larger scale Boeing....
