Yes, I expect so. With 0.041" wire throughout, the high treble tension will 
be over half again what it should be.

Yes, perhaps one. There are a few others to consider as well.


>Perhaps someone here can advise me?

I'll try. For the scaling, there are a number of us here on this list who 
can work something out for you that will be considerably more reasonable 
than what you currently have. As to assessing the piano in general and 
determining a course of action for repairs, resurrection, and the recovery 
from any other arbitrary improvements made with the partial rebuild, I 
would highly recommend the services of a qualified and experienced local 
technician and rebuilder. A reasonably comprehensive understanding of what 
you currently have to work with is critical to making an effective plan of 
action for restoration. Performance penalties for guessing wrong can be 
both severe and expensive, and are nearly always cumulative with each wrong 
guess.
