These suggest that the piano might be 1865, but the page explains that it is unwise to rely purely on numbers to date a piano. Are you able to post photos here to show what the whole piano looks like?
No archives are known to survive for their London pianos, and it is not possible to trace individual London pianos unless they happen to appear in Paris archives. See the notes near the bottom of the page at
So far i found j.pape etched onto wood under the soundboard i presume a factory worker also any ideas on the signature i have uploaded pics regards !
They are not really splayed! Look up the meaning of the word. The dates I published are based on definite dates imprinted inside London Erard pianos.
It may seem that Pierce is "the bible" but it ain't necessarily so! The dates I gave are perfectly reliable when you allow for the fact that, because making a piano was a long process, you can't pin it down to a single date anyway.
There were a few differences between the pianos made in Paris and those made in London, but in general, the models on offer were similar. Regarding upright pianos, the Paris workshop made only a dozen of them between 1824 and 1834. These had a vertical stringing. The real production started in 1834 with a small upright with vertical stringing and 6 octaves. The first oblique uprights, with 6 1/2 or 7 octaves were made from 1839. Clearly, your piano looks more like he was made in the 1860's than 1830's, as Bill already said.
J. Pape sounds certainly more French than English. The actions were sometimes made in Paris, but in the name would be written on the action. If it's written elsewere, it means that J. Pape was in London.
Regularly during the 19th century, the numbering of Erard pianos made in Paris was offset by 1000s to account fot the pianos made in London. Therefore, a detailed study of the Erard Paris archive would probably confirm the numbers for the London pianos given in Bill's website. Just wait for the next rainy weekends. I may be bored enough to study these.
Is your piano in England ?
