Any chance you can let me know if you think this piano which was my grandmother's and in the family for an unknown number of years is possible to date?
It has a number inside the left panel and two medallions inside the top lid.
I have read some of your other forums to try and get some advice.
I would guess this piano was made around 1903, so it should have a number something like 17,000.
Another approach is to get your tuner to remove the action (the working parts of the action| and see if it is marked on the back with the action makers' name and number, which I may be able to date.
