Bill it took several years to find the 10 center, which without a doubt is the hardest of the three to find. I`m not sure where I got it, I believe someone on the board sold it to me. I think mabe Jim Follis sold it to me for 30 or 35.00 Not positive. But its in excellent condition. The last one I saw was on the gentleman from Austraila, Tim, I believe his name is. I missed out on that one. Ron
