Sega Trackball x 2

Two original Sega arcade game trackball controllers.  Definitely something we don't come across much, these trackballs were made by Sega, we believe they are from a dedicated Major League cocktail arcade game (we owed one many years ago).  Trackballs look to be about 2 1/4" size (similar to Centipede).  Note that the black shell on the one is cracked a bit but may be usable given some work. They are untested and sold as-is, they will need to be restored and are complete.

Original Sega Part #610-0013.
