When doing a concours restoration, documentation is one of the most mitigating parts of the restoration. Making sure you put the car back to as close to original as possible depends on documentation. I can't say I was perfect at it, but I was successful at uncovering some unique factory markings on my car which will make the restoration look that more authentic when finished.

There was, of course, much more to my car than this, but these are most of the pictures I took. Alot of knowledge was gained prior to restoring this car from restoring so many others. If I had to guess I would say I have been involved in 20 or more restorations. Most novice restores will find it beneficial to be more thorough than I was.
