The 5 Window Coupe has a trunk and plain front fenders, no cowl lights. The Deluxe 5 Window Coupe has side mount fenders, cowl lights plus a few other accessories added at the factory. The Sport Coupe is a 5 window coupe with a rumble seat and not a trunk.
Your car is a 1932 model year (BA) was assembled in plant # 1 Flint, Michigan in January (month 01). It was the 6449th 1932 assembled in the Flint factory (car numbers began with 1001). Apparently someone has changed the wheels and tires as it should have 5.25x18" tires and wheels. My records show 26623 Sport Coupes (including Deluxe) produced during 1932 model year. The Deluxe 3 Window Coupe is shown as 2226 produced. The 3 Window Coupe only had a trunk not a rumble seat.
