This interesting Clementi carries the stamped number 8800. It is remarkable for its compact size - just 4' 6" long (1370 mm), even more so when we see its six-octave compass, that in itself is unusual for this early date.
Beautiful real gold name motif.
Note the unusually large 'additional keys' section, to give a reasonable soundboard area.
This is a challenging restoration project, but surely worth doing.
