Good question on the '57 Widow cars as I believe the model year the Copo designation was first used was 1958?.
Also didn't SO in 'Copo & FSO' refer to Shop Order not Special Order?.

Weren't the black widows "technically" built by SEDCO at Nalley Chevrolet, and not G.M.? Maybe because there was no well established COPO process at the time?
