I looked at three Lyon & Healy string gauges recently, all from 1911, and there were three different gaugings among them. The same string would register as 2d octave g, g#, or a, depending which gauge you used. I remember Miss Lawrence saying that they always used their gauges to identify strings, they weren’t packaged, I think. I don’t think one can make any unilateral statement about the gauging of harp strings in that time, then. They would have been lighter and the same or heavier, depending on the gauge one used.
