Mason & Hamlin Model 50

[Delwin D Fandrich]

We can tell nothing without string lengths. 
 
If a piano is worth restringing it is worth rescaling.

List,

 

I am rebuilding a Mason & Hamlin Model 50, serial number 83207, built circa 1978
with a strange stringing scale.  I would like to know if I should restring it as
it is marked on the plate, or as it was measured, or if it should be rescaled.
If it should be rescaled - what is the best proceedure?.

 

Wire size:    Scale on plate:                As Measured:


 13                7 unisons                        7 unisons
 13.5             4                                    4
 14                4                                    4
 14.5             4                                    4
 15                4                                    4
 15.5             8                                    8
 16                8                                    8
 17                10                                  10
 17.5                                                   8
 18                8                        
 17                3                            16.5- 3
 
The piano has always been poor in terms of tuning stability.  What do you think?
