Regarding the piston aircraft MiG15 kill(s), I seem to recall a USMC Corsair claimed a MiG kill as well, but can't recall any details.
On September 10, 1952, Captain Jesse Folmar of Marine Fighter Squadron VMF-312 destroyed a MiG-15 in aerial combat over the west coast of Korea.

Re P-51 victory over MiG-15:
Making a quick acrobatic maneuver, “Miss Dee” barely screamed past the MiG at 5,000 feet, so close that the major could see the “ruddy” face of the pilot. He quickly peeled away and ran south. Major Yingling’s wingman saw the MiG pilot bail out of his crippled aircraft — confirming the aerial kill.

Plus several probables listed from other pilots.
