Well, that's a great question and that's another interesting story. Because when I said before that they made it with cane, and bottle tops, and all bearings that went on for a lot of years. And a lot of those people worked in what we called sheltered workshops. And that's what they did, they did cane weaving, and they made them. But as time went on and on, less and less of them, were involved in cane weaving. And so we got to a stage probably in the late 70s, where we only had about three ball makers. And we had every state playing blind cricket and they couldn't keep up the demand. It just got too much for them. Because they used to make these balls by hand. And the strength that they had to have would, you know would take them two or three hours to make one ball. So you can imagine if we've got you know, teams playing every weekend. There's a lot of balls required. So, they went away from the actual and the other thing too was the cane ball had to be soaked in water otherwise it would crack. So you almost had to have two balls per game. And you had a can of water behind the stumps at the non bowling end. And at the end of every over you would put the ball in that of water and take out the other ball that was in there because one over was enough it would crack if you didn't if it would crack if you didn't keep it moist. So they went away from there. In the 80s in the late 70s, early 80s, they decided to go to nylon. And that's when people like David Sloan, there was another guy called Ian Walsh. I think you met Ian Walsh at the World Cup. He was a B1 from Australia. He was a ball maker. Doug slam was a ball maker, another guy from South Australia called Lynn Clothier was a ball maker. So they found that they can make the balls as good as the cane ball if not better. But the thing was, they lasted a lot longer. So, the demand could keep up with supply, whereas with cane balls, it couldn't keep up. So they evolved that through to the nylon ball,same design, only it's used with a different, you know, still got live shot, lead shot and bottle tops in it. But it was just designed a little bit differently. Anyway, then, this was a very demanding skill on behalf of these people making. And as they as they aged, the skill wasn't being passed on to other people. So Trevor Vairo, and myself, saw that we were going to have a real catastrophe on our hands that we were going to run out of cricket balls. So we actually, we actually got onto somebody in China, we sent them the design under someone in China, he could make a prefabricated ball out of woven plastic, which wasn't actually woven like a cane ball, but it was all the same features. And still, we had the lead shot and the bottle tops. And so we got on to a developer in China. And that became the source of our balls for ongoing cricket. But as you know, at the, I think it was the 2004 World Blind Cricket Council meeting, there was a great discussion on the ball. And the preferred way, I mean, even back at the 1998 sorry, 1996 meeting, we decided in Delhi to go with what we call the Indian ball, which was the Indian Pakistan ball. And that became the world ball then people did try and change it over time, but it never ever succeeded. And so a lot of our players in Australia now played with the the Indian ball. But some of them still have their games occasionally with the Australian ball.
