You are indeed correct.
A lot are missing. Who wants to put the car in reverse, just to get the key out. A pain in the @ss if you ask me. Especially if your A833 is a little worn out and is hard to get in reverse. Or those straight cut gears are not lined up exactly.

There are originals for sale (usually not complete) and also reproductions.
