Wow! I think you nailed it! I had a list of about 5 or 6 dealers in the area whose names ended in "ON" including Ryerson, Fulkerson, and a few that were So-and-so & "SON", etc. With all of the research, none of the fonts seemed to match up. I had not heard of this particular dealership until now. The original owner's brother said that the car came from a dealer in this area, so this all adds up now. Thanks for your help!
