Dan, To convert your string measurements to mm, multiply your mircometer readings by 25.4. I have restrung English uprights from this period and wonder if you have anticipated the problem with the pinblock. Loose tuning pins are pretty standard on these instruments and restringing with oversize pins does not always correct the problem. The pinblocks are solid wood and the cracks will just open wider when a larger pin is used. Then there's the problems with the nut, which is often made of wood that is cracked. Bringing up the string tension of a piano with this condition causes the nut pins to pull out and fly across the room like bullets. Then there's the action..... I really don't think you need to worry about what kind of wire you are using. It is unlikely to make any difference in the tone of a piano like this. Good luck, Ken Eschete >Kenneth, > > I did not find string or gauge size on the frame or bridges etc, I miced >the wire. Do you know how American Standard gauges relate to Metric?
