Jim, I'm no help to you, but that is one gorgeous car. You can probably count on it being hard to find, but I'm sure if anyone can, it's you. I wish you all the luck in the world.
I now have it traced down to a dentist doctor, all the way back East in Pennsylvania.
But there are two of them by the same last name.
Must be a father and son.
But calling phone numbers, you don't get a dentist's office, but a large central medical office for practicing dentists, back in that part of PA.
I'll do some more research, or someone might chime in with info that i am looking for.
