Looking for the power switch cover (5200 2-port version)

I'm looking for power switch cover (plastic part from the top of console). I'm a rookie at Atari 5200 and when buying a console, I did not notice the lack of of this part. I have not looked closely enough at console pictured in the auction and this part is not in the console actually.

Would someone sell me this part (if someone has this power switch cover unnecessary or he has damaged housing)? I would be eternally grateful.

My console (photo from the auction) and picture from 5200's FSM.
