Authenticity Company

[f68yenko]

I have a question for anybody who is familiar with cars that came from Celebrities or had some need of paper work for authenticity, especially in California.
In the early eighties I paid a company in California for Authenticity and records that were notarized and kept on file with them on vehicles and motorcycles I purchased from celebrities and were used in movies or in a historical event.
Does anybody know off hand the name of such companies especially in California.
I am stil trying to receive my files and documents from a previous girlfriend and am having trouble locating her because of the time frame.
Any help is appreciated. THANK-YOU
