COB is the AC Cars equivalent of Shelby American's CSX serial number prefix. All original Cobra bodies and chassis were manufactured by AC in England. The ones bound for the US to be finished and sold as Shelby Cobras had serial #'s beginning with CSX. The ones completed by AC for sale in the UK (with parts and drivetrains supplied by Shelby American) had serial numbers beginning with COB. They are more than "accurate". They are every bit as much an original Cobra as the ones sold by Shelby. They are "AC Cobras" as opposed to "Shelby Cobras". Having said all that, I think the new Cobras sold by AC also carry the COB number and the pedigree and status of some of the various incarnations is highly debatable.
