A.C. Cars Ltd. looking for info

[adv-ent]

1ntCobra, OK, thanks no problem.
I have checked everywhere, there are no numbers on the door hinges, I was even asked to check the drivers side rear frame rail end cap where I was told Kirkham sometimes stamps there numbers. There are no numbers anywhere other than the 0666 on the inside of the trunk clasp that I can find.
I even looked very closely to see if maybe original number have been removed but the paint seems original and is in very good condition and nothing seems out of place.
The biggest mystery is why anybody would use the COB 0666 number if it is a known fact that this number never existed and especially when all the original cars chassis numbers seemed to start with 6. Seems like a pretty stupid choice.
I have collected WW2 militaria for years and run into fakes all the time but most fakes encountered are at least not so obvious.
Unfortunately there is no longer any information of the previous owner, I traded the car away and never thought I would ever have a chance to get it back so until a couple of weeks ago it was lost to me. This is why I now am looking for info on who made it because it is now mine again. I can't even remember exactly when the car was purchased, my car is now over seven years old and the aluminum body was purchased before my car was started.
I do know it was not purchased from any kind of manufacturer but from an individual. It was picked up in Malibu Beach from a storage facility.
