Odds are, you'll get away with it, but can you tell how overbuilt the plate is by looking at it? >Is plate > damage the greatest risk involved in this +50 scenario?

The potential problem will be in the small wrapped strings that are already well over 60% of their breaking strength at 440. It might be just fine in some pianos, and damaging in others. Again, odds are it will probably be fine, but do you know the margin you have to work with? And who takes the responsibility for guessing wrong? Ron N
