Often known as "hoop and spike" clocks because of the iron hoop to hang the clock from, and the spikes at the bottom to dig in the wall and keep the clock steady. From now on the timekeeping of clocks improved by a huge amount using the longer pendulum and "anchor" escapement.

It is extremely important to remember that there are always exceptions to every rule, and unfortunately, there are lots of exceptions. Each clockmaker was an individual; he may have followed general styles and tastes, but he invariably also exploited some of his own talents, individualism and preferences. We can also be reasonably confident that the clockmaker and cabinetmaker, who made the case, were not the same.

These were likely different tradesmen, right from the earliest times. Only the clockmaker signed the clock, and usually, just on the dial.

These clocks demand considerably less value than a clock where all of the parts started out life together, as just one original clock. When buying therefore, it is best to approach a reputable dealer, or to learn the identification process yourself. So where should we start?

We must judge whether they are contemporary, whether they belong together, and whether they likely started life together as one clock. If all of the feasible date ranges for all of the components overlap, there is a good probability that you have an authentic clock, not a marriage.

Such a clock could be quite valuable. The date of a specific clock would usually be within the overlapping period, but generally toward the most modern or latest dating component or style, figure 2.

We must consider that the maker may have carried over older designs, parts or styles, or was just using up old stock. Since George Prior is such a well-known and respected maker, I will cheat a little: George Prior is recorded as a London maker, well known and distinguished, a supplier to the home, English market, and to the Turkish market.

We do know that brass dials all but ceased in Victorian times, being replaced by painted dials in the late 18th century and beyond. Arch dials began about and continued as the preferred style through to current times.

The hands are non-matching steel. Matching hands started about the same time as the painted dial, in the early s. They were initially steel but migrated to brass, particularly for painted dials, by c Beforehands were non-matching and made of blued steel, figure 3.

London swan-neck cases are known, but they are very rare. Most London clocks of the time have arched or pagoda tops, figure 6.
