Back in the day when there were only WGT balls, there were various colours just as there are now with those WGT balls.
Do you believe that the ball shown above could be a left over ball from when a player could pick them up? I also seem to think that the player could not pick up a ball unless they had a bag.
Do you, or anyone else reading this, know anything about this? If anyone has actually picked up a ball, it would be great if you could chime in.
