Indianapolis, I had a similar dilemma that I posted here awhile ago. I have the 35 cabriolet that my parents owned since the early 40's. My dad made changes to the car over the years and it was the families daily driver as the 4 of us kids were growing up. A lot of family history...unlike your circumstance. I restored it several years ago and made a few changes to get it a few steps closer to original. My question here was, now that I've got the money, should I put it all the way back to original. The resounding response was to preserve the family history of the car, to keep it the way my dad had it because the story of a car (provenance) is as important as the car itself. I read your story and, there may be no family ties, but it's the story of the car and the story has a lot of age and had me really interested. As the new owner, it's your duty to preserve the story and preserve what you have the best you can. You have a vintage "race car" so preserve it as that and be proud of and enjoy it. I'm leaving my Cab close to the way that my dad had it and...yes, I'm proud of it even if it's not the way it rolled off the line.
