Here is one of the two fellows I mentioned earlier. Each of these was cast in two parts out of Bronze, and machined. One has to admire the level of effort that went into making and installing them, all for naught. The agraffes, also pictured here, are all too badly damaged to be reused. They were all drilled out, in place, to accommodate larger modern wire.
All the string lengths, the strike line spacing, and the string heights were recorded, before the instrument was unstrung. For those of you more fastidious than me, I did keep the wire and the pins, although they are modern, just to have a record, and to know the string tension on the instrument when it first arrived.
