3" Trackball Lot x 3 (Orange, Blue and White)

Lot of three, 3" trackballs in Orange, White and Blue that were never used. We purchased these years ago from Happ Controls for restoration projects (likely Marble Madness).  They have been sitting in a bin since then. The white one has some lighter wear, but none of these were used and would be great for a restorations. Listing is for the three balls as shown.
