I was given this clock by my mother, who bought it in London 20 years ago. I was able to find a restorer and now the clock functions well. I was hoping that the restorer would find some marks but unfortunately there are none. It stands 28cm high. Can you give me some idea of its origin, date and value?

Your clock is almost certainly French, dating from the latter part of the 19th century, and made for the English market. The case appears to be made of sheet copper or possibly tin, with embossed mounts. The whole thing has then been silver plated.
Over the years, the silvering has naturally oxidised, giving rise to the purplish tinge. The dial, which has been protected by the glass, gives an impression of the original colour. Its value is in the region of £300-£400.
