I, too, have a Wurlitzer grand with the split pins. It's a 6-footer from the '20s, and the pins are tight. Wurlitzer also put this system in uprights. One complaint I heard was that the plate pulled forward some on a Wurlitzer player. Perhaps it lacked the firm attachment to the back a pinblock gives. The company mostly used the standard block, of course. Philip Jamison West Chester, PA
