This clock is unsigned, but is most likely by Robert Roskell. It is a two
train, eight-day lever and balance wheel escapement. Escapement is fully
jeweled.
This clock follows a design made famous by the Condliff family in their
series-one clock designs. These have the movement held aloft above the base
by pillars. In between is located the escapement consisting of a lever
escapement controlling a balance wheel. Most often a sculpted snake slithers
on the base with its mouth holding one end of the helical balance spring.
This example has a set of tapered, fluted pillars and unusual tapered
shaped plates. The fly governor for the strike train is a vertical arbor,
'helicopter' design.
The clock is set upon a tall octagonal base with brass octagonal glass
glazed case. The effect makes what is a smaller clock look much larger.
However, this is deceptive when it comes to how heavy this pice is. the
clock alone weighs about 20 lbs, with case and plinth about 35 lbs.
