And another Mantel clock. This one was a wedding present for the younger brother of the little girl in Mantel clock no.4! Perhaps not quite as complex to make as no. 4.
This style is based on the chamfer top clocks, which were popular from around 1810. This one is made from solid unembellished Jarrah. Though it does have a typical period Pineapple on the top, and Lion head drop handles on the sides. It houses a Hermle pendulum governed ting-tang movement. Hence the window on the front to see the pendulum, and the brass frets on the sides.
However, the the window to enable you to see the pendulum is not a feature of genuine clocks of the period, though it would have been seen through a longer full length back door. All these early clocks would have used a pendulum regulated movement. The balance wheel mechanism a carried over from pocket watches became used in high grade carriage clocks later in the 1800's.
Yes 250mm tall and 270ish wide. The Hermle movements brass plates are 100mm in diameter. But it's finding the right dial that really governs the size. Get the movement and dial first. Some larger bracket clock movements come complete with dial.
