Boris- Welcome to Commander world! If you can search for old posts on the topic of flap indicator you will find many discussions on the part you are missing. I recently had to remove mine for a solder repair.
I'll bet the previous owner had trouble with the part and removed it for repair. Probably couldn't fix it so he didn't re-install. Good luck! k
