Though the warping would probably have happened at the time the plate was cast. It is fairly common to find plates warped across the tuning pin panel as a result of uneven cooling. The usual fix would be to put a reverse warp in the pattern. It sometimes took a while for foundries to get this just right but in the meantime the piano makers often went right on building pianos. It is odd to find it blocking the removal of the action, however. Warped plates look a little weird but they are usually stable. Before condemning either the piano or the plate I'd want to look for other reasons why the action doesn't want to come out. Like action glides, a warped keybed, etc. Del
