Mr. Richard Arnold has a bracket-clock by Knibb which also strikes in the same way. It is illustrated in Figs. 403 to 406. The same peculiarity of the " IV " in the dial numbering will be noticed. It is difficult to understand the reason of this striking in a bracket-clock, the striking-duration offering no problem, as it does in the case of a month long-case, especially when of small size. Actually, the going train of this clock requires to be wound five times in the same space of time as the striking train is wound twice. The system, therefore, in the case of this bracket clock, can only have been a conceit.
Fig. 407 illustrates two features which are rare on bracket-clock dials, and still rarer in the case of long-case clocks. The hour ring is cut away between the numerals, showing the matting of the dial underneath, and every minute on the outside of the circle is separately numbered from 1 to 60. This is technically known as a minute-numbered skeleton-dial. The pattern of the corner-pieces and the style of the case, veneered with laburnum and inlaid with simple marqueterie of stars, fans and jessamine leaves, indicate a date not later than 1695 and possibly some ten years earlier. The movement is a month striker. The case measures 6 ft. 8 ins. in height. Fig. 408 is another skeleton minute-numbered dial from one of Joseph Knibb's bracket clocks, which shows the detail more distinctly.

While clocks of the type of the last five examples are rare and valuable, it is possible to procure more ordinary, but still very refined specimens, at quite a commercial price. It must be remembered, however, that these early clocks were, until quite recent years, very scantily appreciated, and have by no means reached their true value. Nothing could be more refined and pleasing, as articles of furniture, than the simple walnut long-case clocks such as Fig. 409. The movements are almost invariably of good, if not fine quality, the cases are usually of small unassertive size, and the clocks fulfil all the requirements of ordinary good-class furnishing. The collector, however, should learn to recognise a good clock at a glance. The appreciation of the following points should be practically instantaneous. The clock should be an eight-day, at least; thirty-hour clocks are worthless. It should have a striking train, - unless there exist sufficient reason to the contrary, as in the case of Fig. 394, - with both trains winding from the front of the dial, and the hands should be well pierced and of the pattern of the period of the clock. A study of clock-hands may be made, with ease and advantage, by the collector.
Several typical examples are illustrated on pages 341 to 343, and each clock illustration furnishes one pair, which can be examined with a magnifying glass. Corner-pieces maybe of several patterns, but if they are merely rough castings, without chasing, they are subsequent additions, and it would be advisable to suspect the entire clock. The hourring should be silvered, - unless the silvering has, obviously, been worn away, - and the minute divisions either on the extreme outer edge, or if set inside, with an additional space outside for the Arabic minute numerals, neither the space nor the numerals should be large. Coarse minute numerals indicate the late degenerate country-made clock.
