39 Cabriolet Rear Handle

[Gary-UK]

On my newly acquired 39 Deluxe Cabriolet, it has in the past had a 32 spare wheel carrier fitted to the rear bumper irons, the "handle" which is normally found on the rear has been removed. Is this handle assembly the same as a coupe or unique to a cabriolet? I'd like to put my spare wheel back inside the car and fit the correct item to the rear of the body.

I can only find reference to a trunk handle with a key, seems strange for them to have fitted a locking handle that did nothing to a rumble seat car. Or am I missing something?
