Info on a P-40C needed

I again have to say that I have never felt so welcomed to a forum and I deeply appreciate it. I am also amazed by the great well of collective knowledge and, if you will, allow me to take a little more advantage of all that united brain power…

I am looking for the serial number of this Curtiss P-40C:

In said article it states that the aircraft served with the 20th. Pursuit Group and I’d like to track down where and when.

Thanks in advance and again, thanks for the warm welcome! 🙂
