Nah, Ed....not worth the time & money for a car I'm building to sale...I know it was Teal Blue originally & had Autumn Leaf interior (that was the only option for Teal)...somebody who's buying a finished car to drive & enjoy isn't usually interested in the Heritage certificate...a real collector who's gonna build the car himself might want to know that info before he starts if he can't figure it out himself but most guys aren't that interested.
...&, I've learned a few tidbits about the certificates over the years: "Garbage In, Garbage Out"! BL didn't keep real good build records - neither did MG - so, sometimes the certificate has, how shall I say this, less that reliable information as to actual build data...the Heritage uses old facotry files which are full of inaccuracies (&, they are the only records available!)
