I've got one of these in a college. It's used up, and needs your basic Mark X Full Frontal Rebuild, including soundboard, but it's everyone's favorite piano because it's the only one in the place that doesn't clang painfully (comparatively). The thing I'd be most concerned about is the 45° counter bearing angle in the V bar sections. It just wasn't a good thing to have designed into the piano in the first place. The one I service is virtually untunable, and produces at least a couple of broken strings per year just from that. I'm planning a little creative modification there if the sky ever opens up and enough money falls out for them to get the rebuild done, since that's apparently what it will take. I haven't specifically looked at wippen replacement details on this one, but I don't recall noticing anything insurmountable. If there's a problem there I don't know about, I'd like to hear it too - just in case the sky opens up. Ron N
