What years were the Ford Model T center door sedan made?

The Ford Model T center-door sedan wasn't officially designated as a "center-door sedan" by Ford. The Model T didn't have a standard body style called that. However, some aftermarket coachbuilders created Model T bodies with center doors. There's no specific year range for these conversions, as they were made sporadically throughout the Model T's production run (1908-1927). So the answer is 1908-1927, but it's important to understand these were not factory-built cars.
