June 1974
Bill says:
"BN 1796, former GN 723, a late phase GP9 built in October 1957, was caught resting at Wenatchee, WA, part of a helper set, in early June 1974. This unit seemed to hang around northwest Washington, often in helper service. By 1977 GN's simplifed scheme had been replaced by BN green."
