12/22/2006. Remarks by Johan Visschedijk: "Manufactured as a L-20A (redesignated U-6A in 1962), with s/n 58-1986 it was delivered to the US Army on February 17, 1959. It went on the civil register as N67044 on May 6, 1975. That registration was cancelled on June 1, 1979, whereafter it appeared on the Canadian Register as C-GWPF. In August 1989 it was stricken from the Canadian register and became N450DB on the US Register. On December 6, 2004 it was reregistered as N67667."
