Prepare yourself for the possibility of a sticker action. The one Ibach which I service has this but does not use a rocker, it has a turnbuckle between the wippen and the wooden 'clip' which seats in the center pin mount on the key. I have found this system to have less friction than a capstan/cushion arrangement and adjusts well and maintains it without problems. As far as aftertouch, these hammers are worn be as I recall there is the standard operational 'feel' to it. So aside from the possibility of this sticker, it is a normal action and should operate as such given optimal working parameters.
