In your pic with your post Atryman those are the round dials that CO
has in all their -300's now, the EFIS -300's are all gone, and that is the only plane they have with round dials!
The weather radar and TCAS are combined in a in reply 1 just above the trottle levers, right of the speed brake and left of that flap handle.
IRC the CO
-300 round dials have always been configured with the weather radar and TCAS in same spot.
Hope your enjoying home this weekend!!
