There is one pedal, operating the dampers, on the left of the opening.
The range is six octaves, F1 to E7.
The address on the nameplate, No. 6 Rue de Harlay, allows us to date the piano, as it has no serial number. Soufléto moved to Rue Feydeau in 1830.
With the front panel removed, it is possible to tune. Note the wooden knob at the far right top.
When the wooden knob is raised, a metal retaining rod is pulled from its slot, allowing the piano to be opened for service.
