This is a fun topic.....I guess it's because there are so many "A" lovers on here. That's great.
As far as I know Ford made A's in three coupe bodies...
1. Regular 5 window all steel except for the area above your head like Todd's.
2. Sport/Business coupes are the same except Sport has landau bars and the Business has little oval quarter windows. They both are like the Cabriolet except the doors are solid, tops don't go down, and unlike the cabrio. they have visors. Mine is a Sport coupe.
3. Special Coupe (some call it a leatherback)....basically like the 5 window
except the entire roof is covered with the old Cobra grained oil cloth. That area between the quarter glass areas on yours was all wood. I only learned this about five or so years ago when I put a Lebaron Bonney top on one. If that belt moulding around the bottom roof area is removable, that is what it is...A Special Coupe.
Here's a bunch of really good start to finish pictures of a restored one...

http://www.fordwood.com/spec1928-29twk.htmI'm not really sure if they are any more collectable than a regular 5 window or not. I know I have only seen one and I've looked at a lot of A's (cars too).
You know if you just wait and build this thing when you get old....you'll probably have shrunk a couple inches or so.....
Later....Jake
