Some history:
The P-51H was a lighter mustang than the iconic P-51D and also one of the fastest piston-engined aircraft, it was originally going to fight in WWII against Japan, but it had arrived late so it was not seen. none in action in the war, also it didn’t participate in the Korean War, the P-51D was chosen instead because there were more P-51D than H. The P-51H was used in many units of the US Air National Guard.
