Not all originals had gapspacers. Some had a wooden gapspacer.

*If* you want to add one it is generally not impossible, even as a
retro-fit, to do so, and cram together the stirnging on either side.

I don't think that is an issue.

As I said last message send me the stringing data and I'll put it into my
spreadheet.

Is that the pinblock material at the moment? Whatever repair is eventually
done, differences in material cost will turn out to be negligible. It is
pretty much negligible in the cost factoring for an original reproduction,
too. Money all goes to the labour.

With this Zucky piano authenticity is a secondary issue, since it is a
modern hybrid by design anyway. It is more important to adapt and get a good
tone out of it. Rememeber it is over-built, not under-built, and tends to
sound constipated.

Tell us who that is.

Such a repair should not be refused (barring time constraints), unless they
don't think they can improve it, and are advising the owner that the repair
is not justified.

> So, if I can make it work again, I can live with the loss of authenticity.

Definitely the _main_ issue - make it sound better.

I think you need to analyse the instrument as a whole to see where efforts
would best be addressed and moeny spent.
