Sherman M4A3E8
T98 We had to maintain a precise gap to allow use to insert the balls and the retaining racks. Each rack held ten balls. The racks have a top and a bottom. We were not sure wich way they went but fortunately we got it right. I know if you get them the wrong way they will bind. They have a small brass tab that goes to the bottom, look carefully and you can see it in the pic. This was not clear or stated in the manuals.
