Ric, There's no picture to confirm an actual wipp assist spring, but in the Steinway Patent section of their webpage there is a reference to "grand piano action with support spring to lessen the weight at the inner ends of the keys" July 15, 1882 - C.F. Theodore Steinway. Looking further back, there's "grand piano action with adjustable balance spring to lessen the force needed to depress the key" May 24, 1871 - C.F. Theodore Steinway It would be interesting to see these drawings but it sure sounds like the same concept.
