Yes, François, it is difficult to see how this would function as a tuning peg.

<p class="yiv8702997025MsoNormal">Dear all,</p>
<p class="yiv8702997025MsoNormal"> </p>
<p class="yiv8702997025MsoNormal">I am circulating this object on behalf of Charles Kightly. It was found in St Denys churchyard, York UK. The current mediaeval and Victorian church stands on the foundations of an Anglo-Scandinavian church of around 950AD, below which is
a substantial Roman building that has produced a 2nd-3rd century altar. There is no real dating evidence for this piece as it was found in heavily disturbed soil, just below the surface of the churchyard. Other finds in the area ranged from sherds of Parisian
ware Roman pottery, 17th century pipe bowls, an 1860s perfume bottle and a 1920s lipstick holder. So there’s a wide range of possibilities.</p>
<p class="yiv8702997025MsoNormal"><br clear="none">
</p>
<p class="yiv8702997025MsoNormal">The object has maximum dimensions of length=42mm, height=22mm, width=6mm and looking at the bone structure (from the photographs) I think it could be cetacean bone.</p>
<p class="yiv8702997025MsoNormal">It is described as a ‘Bone decorative fitting fragment, comprising of a decoratively cut sub-square plate with incomplete tubular extension at one end with internal screw thread’. There are only parts of two grooves of the screw thread
surviving. It has been interpreted as possibly a tuning peg for a musical instrument and it is suggested that because it has a screw thread that it probably dates from the 19<sup>th</sup> century onwards.
</p>
<p class="yiv8702997025MsoNormal"><br clear="none">
</p>
<p class="yiv8702997025MsoNormal">Charles asks if anyone has seen anything like this, of any period, and for opinions as to whether it would function as a tuning peg. He also points out that hand-cut screw threads are known from at least the 16<sup>th</sup> century so if
this is hand cut the object could be earlier in date.<span style="">
</span>Has anyone seen examples of bone objects with screw threads earlier than the 19<sup>th</sup> century? How easy is it to distinguish hand cut from machine cut threads? I’ve seen lathe turning evidence on Roman bone objects and plenty of Victorian composite
objects where bone components are joined with screw threads but when does this practice begin?
</p>
<p class="yiv8702997025MsoNormal"> </p>
<p class="yiv8702997025MsoNormal">All the best,</p>
