help about chappell pianos

[Gill the Piano]

Can't tell you what it's worth; get a tuner in to have a look, as you need to know its condition, if it's tuneable, if it's at concert pitch, what state the casework is in, how worn the action is...all sorts! Also basic facts such as size and type of wood used on the case - usually the first thing people ask!
The number would imply about 1876 or so as a date.
