The COB & COX numbers ran concurrent with the CSX production, they were just not for the US market. I`m in work at the moment so can`t 'reference' the details, For a full list of Chassis no`s & dates from AC`s own production ledger, see the last chapter of Rinsey Mills` book, AC Cobra- The Truth behind the Anglo- American Legend.
I do recall that a couple of the last CSX 2*** chassis were re-designated as CSX 300* and that there is a CS2131,CSX2131a & CSX2131 ( the former being the the `63 Le Mans/Willment Cobra, the second being a similar looking car that used to be owned/run by Bell & Colvill{see latest pics in my gallery} and the third being the Willment Coupe.
There are a few gaps in the chassis number order too, I wonder how many of these may have been filled by unscrupulous "Discoveries" of lost cars?!?!?!
(btw,Evan.....we can get 'uncivil' if we try REAL hard!!!
