Ex N38FF & N36DD (both ntu), El Salvador AF FAS 411, N13410, N6160U (with ID as 44-63769), Nicaraguan AF GN85, Swedish AF 26087, USAAF 44-72483. FAA records do not show a c/n, but gives the ID as 44-13250 (which had been supplied to the RAF as KM693 and soc on 28 March 1946 with no further history known: this is the ID that was given when the aircraft was returned from El Salvador in 1975). The problem with the USAAF serial 44-72483 is that it is the ID given to Jerry Yagen's N51EA "Double Trouble Two". So that's another two Mustangs with an identity problem!
