SME 30/2 Controller

Looking to get some questions answered regarding a 2004 30/2 turntable. The controller has the knob instead of push buttons and I believe it to be the 2nd generation as the box is longer format. Does the latest controller work with the existing motor?

 The O-Rings are original and the table has been in the box unused since 2009. Is a belt and new rings needed because of age?

 The platter is the mustard/green color but it seems that it was not a change other than color.

 If anyone knows pricing please enlighten me!

 Thanks for any help.
