David Thompson @ Some Assembly Required (513) 474 1555 or Mark Krotchen @ Obsidian Billiard (513) 724 2700. Both are in Cincinnati. Both cut their own wedges. Sorry I haven't gotten back with you on the rail angle for u-23 cushions. I haven't been able to get the answer yet. Another cushion is the u-56 Brunswick used them and called them a centennial cushion. usually on their lowest end tables in the eighties.
Thanks buddy, Just got off the phone with Mark. What a great guy! He said try Thompson first, which I did. He was away from his phone but I will wait for a returned phone call. I appreciate the refferal and I'm sure they do too.
