Taken from an excellent link that, I believe, straffo found that provides all the text and pictures for "Hanger Flying - complied and written for pilots - by pilots".
Lockheed produced a series of newsletters called Hangar Flying filled with tips and humorous cartoons.
========== Issue 2 ==================
The '38 is a pilot's dream-come-true when it comes to the stall characteristics. They are unusually good and-although not generally used-are worthwhile investigating so that in an emergency you will know what performance to expect from your ship. We have discovered that the power stall occurs at about 70 M.P.H. with about a 50-foot loss of altitude. The counter rotating propellers eliminate torque and there is no tendency for either wing to dip or fall away.
You will find "she" is just as steady in a power off stall with gear and flaps retracted or extended. One of the finest characteristics of the '38 is the accelerated stall. Such stalls, accompanied by normal buffeting, occur on any ship when the angle of attack is increased to the point that the airflow over the wing becomes turbulent.
As you know, this can happen in sharp turns, pull-outs or other severe maneuvers. The '38 is designed to take the buffeting of the stall and has no tendency to fall off on either wing at any altitude. If combat necessitates, you can hold it in the accelerated stall as long as you can take the buffeting -- the ship will take it much longer. To get out of an accelerated stall immediately, ease up on the stick, permitting the airflow to reestablish normal lift.

This is not what I am finding when flying the P-38.
