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? Roger posted that Mertic is .0005 thinner than Imperial. O.K.! Thats 5 ten thousandths. Right? And Imperial relates to American Standard? I could measure the wire witha Metric mic, and end my confusion. FYI, this instrument is an iron frame straight strung birdcage vertical, whose owner could not be talked out of the restringing. The piano is pretty much the garden varaity.) I am guessing it is about 100+ years old, and I am trying to order the correct wire sizes from PureSound. Thanks for your post. Dan Reed Dallas, Texas
