AUJ could have very well been on a mustang flown in the same unit. Each combat unit was assigned a two letter (example: GQ), or single numeral and letter code (example: 5Y), to identify the squadron to which the aircraft was assigned, a third letter was painted to indicate assignment of the individual aircraft to a pilot. The squadron code letters were always painted slightly behind the cockpit area and the individual aircraft letter painted between the national insignia and tail. When there was more than one aircraft in a squadron with the same individual aircraft letter the second aircraft was indentified by placing a bar (-) above, below or even behind the letter. Some groups painted their individual aircraft letter on the vertical fin. In addition, there was a unique serial number painted on the vertical fin by aircraft manufacturers to identify what year the aircraft was funded for construction, followed by airframe production number.
All I was trying to do was show you some Canadian spits with "nose art". I know the camo on the drawings are probably not quite up to par.Nor were they that pretty being painted in the field with a brush/roller/rag whatever was laying around.
