Dave - Thanks for including your photo! - Is it just me or does the oval window in your car looks noticably smaller than the oval glass in another car just a few pictures down from yours in this thread?
If so, was the Doctor's Coupe different somehow from the Business Coupe?...
Could you...
I purchased a pair of beveled oval windows from a lady antiques dealer who said she'd bought them many years ago from a car dealer who figured he'd never sell them... but she didn't remember what kind of dealership it was.
I thought they might be for the 1929 Ford Model A Business Coupe side...
