Mason & Hamlin Model 50

Not much to add to what Del said.  It is always worth a look at the scaling
and there are a few out there who can do it for you, Del included.

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?
