The 1900 series of GMC ‘old looks’ were ordered by AC Transit’s predecessor, Key System Transit Lines in 1948, and was transferred to AC Transit in 1960. Coach #1921 was restored to original Key System “fruit salad” colors in celebration of AC Transit’s 20th anniversary in October 1980, and underwent a more extensive overhaul and restoration in 1995.
