Interesting Problems in a Seiler upright

Did the top of the pinblock area allow for inspection? Dampers not lifting from strings and hammers blocking and all this happening over a short period of time are consistent with pinblock/backpost separation (and pretty major at that). If there is veneer or something covering this area I would suggest measuring the width of the back to plate dimension in numerous places along the top - should be consistent width all along the top. Presumably the pitch would also drop with a moving plate/pinblock. Where was the pitch (and I don't mean low, high, outside, inside or strike or fast or slow!)?

>From your description of this occurring over a short period of time, SOMETHING has moved. Did they mention dropping it down the stairs?
