Ok, I have sorted out the sticking notes so here is the scale compared to my Steinway Grand.
Left side with serial number.
First row on left starting nearest strap. D2, A2, E2, B3
Second. C2, g#2, D# 3, A#3
Third row E2, D2, A#2, F2, Middle C4,
Fourth G2, F2, C2, F2, C#5.
Fifth F#2, C#4, G#4
Sixth row B2, D4, G4, A5
Right side with label and air button.
First row on left D4, A5, E5, B6, G5
Second row C#3, G#3, D#, 5, A#6, F6.
Third row E4, D#4, A#5, F5, C6, F#6
Fourth row G4, F4, BB5?, F#5, C#6, G#7
Fifth row, F#3, C#5, G#5, D#6, ?,
Sixth row, B5, D5, G5, A6?, E6.
The numbers refer to the octaves but are subject to some revision I am sure. Most notes work well in and out, a few have a squeak one way.
