Clock movements dating
The worth (or value) will of course be concluded by looking at the best clocks available in a respectable dealers showroom.
These questions apparently can be answered quickly for some, thus leaving the owner with a date range and usually an over-inflated price.
The clock that I will use to explain the process is a mahogany cased (veneered), brass dial, musical longcase clock.
It has a 12in dial and the clock stands 256cm or 101in high (thats 8ft 5in), and the name on the dial is George Prior, London, figure 1.
It is extremely important to remember that there are always exceptions to every rule, and unfortunately, there are lots of exceptions.
John might also be abbreviated to just Jno and to complicate matters, J and I were often interchangeable, so Jno might be engraved as Ino, also meaning John.
There are many such examples, like W often being engraved to look like an N, or even a U.
In terms of originality however, the astute specialist would quickly question a marquetry, walnut and ebony cased clock with a painted dial.
Originality is critically important, both in confirming the age and in determining the real value of the clock.Each intended use will generate a quite different value for the same clock at the same point in time.As we will see, in properly dating a clock, authenticity or originality is often resolved in the process.Most serious horological books will suggest that the name on the dial should be the last place to start dating a clock.
