Yes. This was a factory option in Late 1931 for Deluxe Coupes with a Rumble Seat.
I have a late 31 Coupe indented firewall car that didn't have it because it had a trunk. I really wanted it and found all the original parts rather than ordering a kit.
It is fairly easy. Remove the wood in your coupe. Tap bottom body flange down. Install thicker Roll Down Window wood. Install thicker rear window metal garnish. Install special shallower package tray with mount for window regulator. Mount glass to window channel and install. Run drain hose out of car from installed window gutter tray. Find correct T handle (similar to rear handle in Fordor but not the same)
The window only rolls down a little past half way. When driving, there is almost no noticeable change in breeze. It's best for being able to talk to someone in the rumble seat. Adding wind wings that you can tilt in to blow breeze in your face is the best way to get more airflow in the coupe.
Here is a kit to do it:
