Hey folks, first timer. Let me be upfront, I do not own a classic Cadillac but have tried to learn about Model 30s, and have learned a few things about other classics as well. I've got a few questions based on what I think I learned but they're only relevant if the Serial number and Engine Plate my Dad had framed is orignal and not a reproduction. I'll attempt to load a resized photo and would greatly appreciate your expertise.
