Sorry for my ignorance but explain: PRN? TAMIU? If all of the Bostons, or majority of them have this stuff...sounds like someone lubed them. The factory isn't going put something in the piano that attracts dust/dirt. These are basically Kawais. You could have dried out pinblocks...Texas. Seems to me Avery can talk you through this...
