Twenty-five bowls mounted on a square section iron axle. On the left-hand end of the axle is mounted a flywheel,
diameter 280mm, made from a lead rim of 22mm square cross section mounted on four iron spokes. The left-hand end of the axle rests in an
'open' wooden bearing slot with a metal lining. The right-hand bearing is closed and made of an iron arch with two bearing blocks of
unidentified material. A curved iron crank (centres at c.50mm) connects to a composite wood and iron rod which in turn connects to the
end of a lengthways wooden treadle hinged to the right-hand end of the stand. The foot 'pad' for the treadle is missing. The axle is
720mm above the floor. The metal water trough is missing - it would have been 950 x 315 by 135mm deep. There is a clearance in front of
the player's knees. Case work and stand appear to be mainly of oak and a softwood. There is a lift-off cover consisting of a sliding
'tambour' of thin wooden slats on fabric. According to the Donaldson Catalogue, 'probably Venetian glass in a German
case'.
