A most interesting situation. I can't imagine anyone putting an action in a piano and then squeezing through tight places to raise the rest rail and then raising the hammers to match it. I'd check the glide bolts. If they are all the way down this would significantly raise the action off the key bed. If this is not the case I'd say either someone or something has changed this piano so that the action is wedged in there. I might suggest inspecting the piano structurally to see if anything has happened to it. See if the key bed has warped somehow. Look and see if the the stretcher is loose or warped, perhaps the pin block is falling apart and sagging. This could wind up being a symptom of a much larger problem.
