Hello, Paul, What sort of action did this have, and was there a scale marked on the plate? The serial number you gave seems too low for a 9' grand, it sounds more like a case number. Pierce presents an 1840's instrument as their first concert sized instrument. I think 33bs have 17 bass, but they're 8'6 and later than the approximate date you gave. Every example I've seen has a Brown action. Clark
