The number of this handsome piano indicates a date of 1843-4, but there is a clear date of 1846 on the lowest key. Was the structure of the piano perhaps made and numbered in the earlier year, but not completed with its action until two years later?
The owner bought this piano about twenty years ago, and it has been in regular use until relatively recently, which is a good omen for its condition.
Please remember that, as usual, I have not personally seen this piano, but the interior pictures do indicate a good condition.
The rosewood nameboard, and ivory and ebony keys seem to be in excellent condition.
This one is in Guildford, Surrey, and the owner, Joseph Dunkley, is asking £600 o.n.o. Please remember, and check with Joseph, but if this one is as good as it seems, then it is a piano to be played and enjoyed straight away (after tuning, of course!)
